## commit_stats
|
||
|
|
||
|
### Instructions:
|
||
|
|
||
|
In this exercise you will be provided with a json file `commits.json` with data corresponding to git commits in GitHub (extracted using the GitHub rest API), your job is to extract the relevant data and place it in a struct called `CommitData` to get the following information:
|
||
|
|
||
|
1. Number of commits per author (identified by the GitHub login).
|
||
|
|
||
|
2. The number of commits per author.
|
||
|
|
||
|
Create two functions:
|
||
|
|
||
|
- `commits_per_author`: which returns a hash map with the number of commits per author.
|
||
|
|
||
|
- `commits_per_date`: which returns a hash map with the number of commits per week.
|
||
|
|
||
|
- Note: A week is represented by the a year followed by the number of the
|
||
|
week for example January 1, 2020 is in week 1 of 2020 an will be
|
||
|
represented by a String with the form "2020-W1".
|
||
|
|
||
|
### Notions:
|
||
|
|
||
|
- [chrono](https://docs.rs/chrono/0.4.19/chrono)
|
||
|
- [json](https://docs.rs/json/0.12.4/json/index.html)
|
||
|
|
||
|
### Expected functions
|
||
|
|
||
|
```rust
|
||
|
pub fn commits_per_week(data: &json::JsonValue) -> HashMap<String, u32> {
|
||
|
}
|
||
|
|
||
|
pub fn commits_per_author(data: &json::JsonValue) -> HashMap<String, u32> {
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a possible test for your function:
|
||
|
|
||
|
```rust
|
||
|
use commit_stats::{commits_per_week, commits_per_author};
|
||
|
|
||
|
fn main() {
|
||
|
let contents = fs::read_to_string("commits.json").unwrap();
|
||
|
let serialized = json::parse(&contents).unwrap();
|
||
|
println!("{:?}", commits_per_week(&serialized));
|
||
|
println!("{:?}", commits_per_author(&serialized));
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And its output:
|
||
|
|
||
|
```console
|
||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
{"2020-W44": 5, "2020-W36": 1, "2020-W31": 1, ... ,"2020-W45": 4, "2020-W46": 4}
|
||
|
{"homembaixinho": 2, "mwenzkowski": 3, ... ,"tamirzb": 1, "paul-ri": 2, "RPigott": 1}
|
||
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
```
