### Instructions |
||||||
|
|
||||||
|
`Result` is a better version of the `Option` type that describes possible error instead |
||||||
|
of possible absence |
||||||
|
|
||||||
|
Create a structure called `Flag` that as the following elements: |
||||||
|
|
||||||
|
- short_hand: String |
||||||
|
- long_hand: String |
||||||
|
- desc: String |
||||||
|
|
||||||
|
This structure must have associated to it a function called `opt_flag` that initializes the structure. |
||||||
|
Receiving two references strings and returns the structure `Flag`. It should be used like this: |
||||||
|
|
||||||
|
```rust |
||||||
|
let d = Flag::opt_flag("diff", "gives the difference between two numbers"); |
||||||
|
|
||||||
|
println!("short hand: {}, long hand: {}, description: {}", d.short_hand, d.long_hand, d.desc); |
||||||
|
// output: "short hand: -d, long hand: --diff, description: gives the difference between two numbers" |
||||||
|
``` |
||||||
|
|
||||||
|
It will be given a second structure called `FlagsHandler` that has just one element: `flags: HashMap<(String, String), Callback>` |
||||||
|
And the following functions associated to it, for you to complete : |
||||||
|
|
||||||
|
- `add_flag`, that adds to the HashMap the flag and the Callback function. |
||||||
|
- `exec_func`, that executes the function using the flag provided and returns the result, that can |
||||||
|
be either a string with the value from the callback or an error. |
||||||
|
|
||||||
|
It will also be provided a `type` called `Callback` being a function that is going to be used in the structure |
||||||
|
and functions above. This function will be the callback for the flag associated to it. |
||||||
|
|
||||||
|
You will have to create the following callback functions : |
||||||
|
|
||||||
|
- `div`, that converts the reference strings to `float`s and returns the `Result`, being the division of the `float`s or the standard (std) error: `ParseFloatError`. |
||||||
|
- `rem`, that converts the reference strings to `float`s and returns the `Result`, being the remainder of the division of the `float`s or the standard (std) error `ParseFloatError`. |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
use std::collections::HashMap; |
||||||
|
|
||||||
|
pub type Callback = fn(&str, &str) -> Result<String, ParseFloatError>; |
||||||
|
|
||||||
|
pub struct FlagsHandler { |
||||||
|
pub flags: HashMap<(String, String), Callback>, |
||||||
|
} |
||||||
|
|
||||||
|
impl FlagsHandler { |
||||||
|
pub fn add_flag(&mut self, flag: (String, String), func: Callback) {} |
||||||
|
pub fn exec_func(&mut self, flag: (String, String), argv: &[&str]) -> String {} |
||||||
|
} |
||||||
|
} |
||||||
|
|
||||||
|
pub struct Flag { |
||||||
|
// expected public fields |
||||||
|
} |
||||||
|
|
||||||
|
impl Flag { |
||||||
|
pub fn opt_flag(l_h: &str, d: &str) -> Flag {} |
||||||
|
} |
||||||
|
|
||||||
|
pub fn div(a: &str, b: &str) -> Result<String, ParseFloatError> {} |
||||||
|
pub fn rem(a: &str, b: &str) -> Result<String, ParseFloatError> {} |
||||||
|
|
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|
|
||||||
|
```rust |
||||||
|
fn main() { |
||||||
|
let mut handler = FlagsHandler { flags: HashMap::new() }; |
||||||
|
|
||||||
|
let d = Flag::opt_flag("division", "divides the values, formula (a / b)"); |
||||||
|
let r = Flag::opt_flag( |
||||||
|
"remainder", |
||||||
|
"remainder of the division between two values, formula (a % b)", |
||||||
|
); |
||||||
|
|
||||||
|
handler.add_flag((d.short_hand, d.long_hand), div); |
||||||
|
handler.add_flag((r.short_hand, r.long_hand), rem); |
||||||
|
|
||||||
|
println!("{:?}", handler.exec_func(("-d".to_string(), "--division".to_string()), &["1.0", "2.0"])); |
||||||
|
|
||||||
|
println!("{:?}",handler.exec_func(("-r".to_string(), "--remainder".to_string()), &["2.0", "2.0"])); |
||||||
|
|
||||||
|
println!("{:?}",handler.exec_func(("-d".to_string(), "--division".to_string()), &["a", "2.0"])); |
||||||
|
|
||||||
|
println!("{:?}",handler.exec_func(("-r".to_string(), "--remainder".to_string()), &["2.0", "fd"])); |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output: |
||||||
|
|
||||||
|
```console |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||||
|
"0.5" |
||||||
|
"0" |
||||||
|
"invalid float literal" |

## boxing_todo |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
The objective is to do an api to parse a list of *todos* that is organized in a JSON file, |
||||||
|
handling all possible errors in a multiple error system. |
||||||
|
|
||||||
|
Organization of the JSON file: |
||||||
|
|
||||||
|
```json |
||||||
|
{ |
||||||
|
"title" : "TODO LIST FOR PISCINE RUST", |
||||||
|
"tasks": [ |
||||||
|
{ "id": 0, "description": "do this", "level": 0 }, |
||||||
|
{ "id": 1, "description": "do that", "level": 5 } |
||||||
|
] |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
Create a module in another file called **error.rs** that handles the boxing of errors. |
||||||
|
This module must implement an `enum` called `ParseErr` that will take care of the |
||||||
|
parsing errors, it must have the following elements: |
||||||
|
|
||||||
|
- Empty |
||||||
|
- Malformed, that has a dynamic boxed error as element |
||||||
|
|
||||||
|
A structure called `ReadErr` that will take care of the reading errors, having just an element called `child_err` of type `Box<dyn Error>`. |
||||||
|
|
||||||
|
For each data structure you will have to implement a function called `fmt` for the trait `Display` that writes |
||||||
|
out the message **"Fail to parse todo"** in case it's a parsing error, otherwise it writes the message |
||||||
|
**"Failed to read todo file"**. |
||||||
|
And for the `Error` trait the following functions: |
||||||
|
|
||||||
|
- `description` that returns a string literal that says: |
||||||
|
- "Todo List parse failed: " for the `ParseErr` |
||||||
|
- "Todo List read failed: " for the `ReadErr`. |
||||||
|
|
||||||
|
- `cause` that returns an `Option` with the error: |
||||||
|
- For the `ReadErr` it must just return the option with the error |
||||||
|
- For the `ParseErr` it will return an option that can be `None` if the tasks are **empty** otherwise the error, if |
||||||
|
the parsing is **malformed**. |
||||||
|
|
||||||
|
In the **lib** file you will have to implement a function called `get_todo` that receives a string and returns a Result |
||||||
|
that can be the structure `TodoList` or a boxing error. This function must be able to deserialize the json file, |
||||||
|
basically it must parse and read the JSON file and return the `TodoList` if everything is fine otherwise the error. |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
For **error.rs** |
||||||
|
|
||||||
|

||||||
|

### Usage |
||||||
|
|
||||||
|
Here is a program to test your function. |
||||||
|
Note that you can create some todo list your self to test it, but you can find the JSON files that |
||||||
|
are being tested [here](https://github.com/01-edu/public/blob/master/subjects/boxing_todo) |
||||||
|
|
||||||
|
```rust |
||||||
|
mod lib; |
||||||
|
use lib::{ TodoList }; |
||||||
|
|
||||||
|
fn main() { |
||||||
|
let todos = TodoList::get_todo("todo.json"); |
||||||
|
match todos { |
||||||
|
Ok(list) => println!("{:?}", list), |
||||||
|
Err(e) => { |
||||||
|
println!("{}{:?}", e.description(), e.cause()); |
||||||
|
} |
||||||
|
} |
||||||
|
|
||||||
|
let todos = TodoList::get_todo("no_todo_list.json"); |
||||||
|
match todos { |
||||||
|
Ok(list) => println!("{:?}", list), |
||||||
|
Err(e) => { |
||||||
|
println!("{}{:?}", e.description(), e.cause()); |
||||||
|
} |
||||||
|
} |
||||||
|
|
||||||
|
let todos = TodoList::get_todo("malformed_object.json"); |
||||||
|
match todos { |
||||||
|
Ok(list) => println!("{:?}", list), |
||||||
|
Err(e) => { |
||||||
|
println!("{}{:?}", e.description(), e.cause().unwrap()); |
||||||
|
} |
||||||
|
} |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output: |
||||||
|
|
||||||
|
```console |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||||
|
TodoList { title: "TODO LIST FOR PISCINE RUST", tasks: [Task { id: 0, description: "do this", level: 0 }, Task { id: 1, description: "do that", level: 5 }] } |

## cipher |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
The Atbash cipher is a encryption method in which each letter of a word is replaced with its mirror letter in the alphabet |
||||||
|
|
||||||
|
Your objective is to create a function called `cipher` this must return a Result wrapped in an Option, this result should return either a boolean |
||||||
|
or an Error being the structure `CipherError`. This structure should be the error type for the function `cipher` |
||||||
|
|
||||||
|
This function should compare the original string wih the ciphered string. returning true if the cipher is correct otherwise the error type |
||||||
|
CipherErr with the a true or false if it is validated and the proper atbash cipher. |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
|
||||||
|
#[derive(Debug, Clone, Eq, PartialEq)] |
||||||
|
pub struct CipherError { |
||||||
|
// expected public fields |
||||||
|
} |
||||||
|
impl CipherError { |
||||||
|
pub fn new(validation: bool, expected: String) -> CipherError {} |
||||||
|
} |
||||||
|
pub fn cipher(original: &str, ciphered: &str) -> Option<Result<bool, CipherError>> {} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|

## error types |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
For this exercise you will have to implement an **error type**. |
||||||
|
|
||||||
|
The main objective is to create a form validator, where you must implement a |
||||||
|
error type. This must validate the password and the first name. The |
||||||
|
first name must not be empty and the password must have at least 8 char and a combination of alphanumeric and none alphanumeric ASCII characters |
||||||
|
|
||||||
|
ex: "asDd123=%" => good |
||||||
|
"asgfD" => error |
||||||
|
"asdsdf2" => error |
||||||
|
"sad_#$" => error |
||||||
|
|
||||||
|
Create a structure called `Form` that will have the following fields: |
||||||
|
|
||||||
|
- `first_name`, that will be a string |
||||||
|
- `last_name`, that will be a string |
||||||
|
- `birth`, of type `NaiveDate` that will convert a string "2015-09-05" to a date of that format |
||||||
|
- `sex`, SexType that must be a `enum` with the fields `Male` and `Female` |
||||||
|
- `birth_location`, that will be a string |
||||||
|
- `password`, that will be a string |
||||||
|
|
||||||
|
You must also implement for this structure a function to initialize the structure, `new` and a function called |
||||||
|
`validate` that will validate the form |
||||||
|
|
||||||
|
For the error type you must create a type struct called `FErr`, that will be the type for the error |
||||||
|
It must have the fields: |
||||||
|
|
||||||
|
- `form_values`, this will be a tuple of strings that will save the value that the user inserted into the form |
||||||
|
|
||||||
|
ex: ("password", "asdaSD_") |
||||||
|
("first_name", "someone") |
||||||
|
|
||||||
|
- `date`, that will have the date that the error occurred in the format "2020-12-14 09:33:41" |
||||||
|
- `err`, that will have the error description: |
||||||
|
- "No user name" |
||||||
|
- "At least 8 characters" |
||||||
|
- "Combination of different ASCII character types (numbers, letters and none alphanumeric characters)" |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
pub use chrono::{Utc, NaiveDate}; |
||||||
|
|
||||||
|

|
// expected public fields |

|
} |

pub fn new(name: String, error: String, err: String) -> FErr {} |
||||||
|
} |
||||||
|
|
||||||

## handling |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
Write a function, called `open_or_create` that as two arguments: |
||||||
|
|
||||||
|
- `file : &str` which is the name of the files |
||||||
|
- `content: &str` being the content to be written into the file |
||||||
|
|
||||||
|
This functions should try to open a file, if it does not exist creates it. |
||||||
|
You should panic, with the error, in case something goes wrong. |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
pub fn open_or_create(s: &str, content: &str) {} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|
|
||||||

```rust |
||||||
|
fn main() { |
||||||
|
let path = "a.txt"; |

File::create(path).unwrap(); |
||||||
|
open_or_create(path, "content to be written"); |
||||||
|
|
||||||
|
let mut file = File::open(path).unwrap(); |
||||||
|
|

## profanity filter |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
Sometimes it is more desirable to catch the failure of some parts of a program instead |
||||||
|
of just calling panic. |
||||||
|
|
||||||
|
For this exercise you will have to create a message blocker, where you must block the word `stupid` |
||||||
|
|
||||||
|
You will have to create a structure called `Message`, this structure |
||||||
|
must have the following elements: |
||||||
|
|
||||||
|
- content: String |
||||||
|
- user: String |
||||||
|
- time_sent: String |
||||||
|
|
||||||
|
The struct must also have a implementation of 2 functions associated to it: |
||||||
|
|
||||||
|
- `new`, that initializes the structure |
||||||
|
- `send_ms`, that only has its implementation type (**self**) as argument and returns an option. |
||||||
|
This function must return `None` if the content of the message is either **empty** or contains the |
||||||
|
word **stupid**. Otherwise it returns the content of the message. |
||||||
|
|
||||||
|
You will have to create two more functions that aren't associated to any structure: |
||||||
|
|
||||||
|
- `check_ms` that receives as parameters the reference to the structure `Message` and returns a tuple, |
||||||
|
containing a `bool` and a `string`. This function will execute the function `send_ms` and if the result |
||||||
|
of the option is `None` it should return (false, "ERROR: illegal"). Otherwise it returns `true` and the |
||||||
|
content of the message sent. |
||||||
|
- `date_format` that creates and formats the date and time that the message was sent, the format should |
||||||
|
look like this: **Mon Oct 5 10:22:19 2020** |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
pub struct Message {} |
||||||
|
|
||||||
|
impl Message { |
||||||
|
pub fn new(ms: String, u: String, t: String) -> Message {} |
||||||
|
pub fn send_ms(&self) -> Option<&str> {} |
||||||
|
} |
||||||
|
|
||||||
|
pub fn check_ms(ms: &Message) -> (bool, &str) {} |
||||||
|
pub fn format_date() -> String {} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|
|
||||||
|
```rust |
||||||
|
fn main() { |
||||||
|
let m0 = Message::new("hello there".to_string(), "toby".to_string(), format_date()); |
||||||
|
println!("{:?}", check_ms(&m0)); |
||||||
|
|
||||||
|
let m1 = Message::new("".to_string(), "toby".to_string(), format_date()); |
||||||
|
println!("{:?}", check_ms(&m1)); |
||||||
|
|
||||||
|
let m2 = Message::new("you are stupid".to_string(), "toby".to_string(), format_date()); |
||||||
|
println!("{:?}", check_ms(&m2)); |
||||||
|
|

let m3 = Message::new("stupid".to_string(), "toby".to_string(), format_date()); |
||||||

||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
You will have to create 3 structures: |
||||||
|
|
||||||
|
- `One`, that contains one element called `first_layer` it should be an `Option` for the structure `Two`. |
||||||
|
- `Two`, that contains one element called `second_layer` it should be an `Option` for the structure `Three`. |
||||||
|
- `Three`, that contains one element called `third_layer` it should be an `Option` for the structure `Four`. |
||||||
|
- `Four`, that contains one element called `fourth_layer` it should be an `u16` that is an `Option`. |
||||||
|
|
||||||
|
Beside the structure you must create a function named `get_fourth_layer` that is associated to the `One` structure. |
||||||
|
This function should return the `Option` value in the `Four` structure. |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
pub struct One { |
||||||
|
// expected public fields |
||||||
|
} |
||||||

// expected public fields |
||||||
|
} |
||||||
|
pub struct Three { |
||||||
|
// expected public fields |
||||||
|
} |
||||||
|
pub struct Four { |
||||||
|
// expected public fields |
||||||
|
} |
||||||
|
|
||||||
|
impl One { |
||||||
|
pub fn get_fourth_layer(&self) -> Option<u16> {} |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|
|
||||||
|
```rust |
||||||
|
fn main() { |
||||||
|
let a = One { |
||||||
|
first_layer : Some(Two { |
||||||
|
second_layer: Some(Three { |
||||||
|
third_layer: Some(Four { |
||||||
|
fourth_layer: Some(1000) |
||||||
|
}) |
||||||
|
}) |
||||||
|
}) |
||||||
|
}; |
||||||
|
|
||||||
|
// output: 1000 |
||||||
|
println!("{:?}", match a.get_fourth_layer() { |
||||||
|
Some(e) => e, |
||||||
|
None => 0 |
||||||
|
}) |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output: |
||||||
|
|
||||||
|
```console |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||||
|
1000 |
||||||

## unwrap |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
It will be given a function called **odd_to_even**, that returns an `Result`. If its an error it will |
||||||
|
return a tuple with a string, indicating the error, and a vector with the elements that justifies the error |
||||||
|
|
||||||
|
The objective is to execute the `odd_to_even` function and handle the error given by it |
||||||
|
|
||||||
|
Create the following functions that receives a vector : |
||||||
|
|
||||||
|
- `expect` that returns the error adding the sting "ERROR " |
||||||
|
- `unwrap_or` that in case of error returns an empty vector |
||||||
|
- `unwrap_err` that returns error if its `Ok` and returns the |
||||||
|
string containing the error in case of `Err` |
||||||
|
- `unwrap` that unwraps the `Result` |
||||||
|
- `unwrap_or_else` that in case of error returns a the vector that justifies the error |
||||||
|
|
||||||
|
### Expected Function |
||||||
|
|
||||||
|
```rust |
||||||
|
pub fn odd_to_even(data: Vec<u32>) -> Result<Vec<u32>, (String, Vec<u32>)> {} |
||||||
|
pub fn expect(v: Vec<u32>) -> Vec<u32> {} |
||||||
|
pub fn unwrap_or(v: Vec<u32>) -> Vec<u32> {} |
||||||
|
pub fn unwrap_err(v: Vec<u32>) -> (String, Vec<u32>) {} |
||||||
|
pub fn unwrap(v: Vec<u32>) -> Vec<u32> {} |
||||||
|
pub fn unwrap_or_else(v: Vec<u32>) -> Vec<u32> {} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function |
||||||
|
|
||||||
|
```rust |
||||||
|
fn main() { |
||||||
|
// this will give an expect error |
||||||
|
// println!("{:?}", expect(vec![1, 3, 2, 5])); |
||||||
|
println!("{:?}", unwrap_or(vec![1, 3, 2, 5])); |
||||||
|
println!("{:?}", unwrap_or(vec![1, 3, 5])); |
||||||
|
println!("{:?}", unwrap_err(vec![1, 3, 2, 5])); |
||||||
|
// this will give an error that is unwraped |
||||||
|
// println!("{:?}", unwrap_err(vec![1, 3, 5])); |
||||||
|
println!("{:?}", unwrap(vec![1, 3, 5])); |
||||||
|
// this will give an error |
||||||
|
// println!("{:?}", unwrap(vec![1, 3, 2, 5])); |
||||||
|
println!("{:?}", unwrap_or_else(vec![1, 3, 5])); |
||||||
|
println!("{:?}", unwrap_or_else(vec![3, 2, 6, 5])); |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output: |
||||||
|
|
||||||
|
```console |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||||
|
[] |
||||||
|
[2, 4, 6] |
||||||
|
("There is a even value in the vector!", [2]) |
||||||
|
[2, 4, 6] |
||||||
|
[2, 4, 6] |
||||||
|
[2, 6] |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ |
||||||
|
``` |
