display_table
Instructions
Define the Table
struct below, and implement the associated functions new
and add_row
. You can see how they should work from the usage.
Implement the std::fmt::Display
trait for the Table
structure so that the table is printed like in the usage. The length of each column must adjust to the longest element of the column, and the element must be centered in the "cell" when possible. If the element cannot be centred exactly, it must be positioned slightly to the left.
If the table is empty println!
must not print anything.
Expected functions and Structures
#[derive(Clone, Debug, PartialEq)]
pub struct Table {
pub headers: Vec<String>,
pub body: Vec<Vec<String>>,
}
impl fmt::Display for Table {
fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
}
}
impl Table {
pub fn new() -> Table {
}
pub fn add_row(&mut self, row: &[String]) {
}
}
Usage
Here is a possible program to test your function:
use display_table::*;
fn main() {
let mut table = Table::new();
println!("{}", table);
table.headers = vec![
String::from("Model"),
String::from("Piece N°"),
String::from("In Stock"),
String::from("Description"),
];
table.add_row(&[
String::from("model 1"),
String::from("43-EWQE304"),
String::from("30"),
String::from("Piece for x"),
]);
table.add_row(&[
String::from("model 2"),
String::from("98-QCVX5433"),
String::from("100000000"),
String::from("-"),
]);
table.add_row(&[
String::from("model y"),
String::from("78-NMNH"),
String::from("60"),
String::from("nothing"),
]);
println!("{}", table);
}
And its output:
$ cargo run
| Model | Piece N° | In Stock | Description |
|---------+-------------+-----------+-------------|
| model 1 | 43-EWQE304 | 30 | Piece for x |
| model 2 | 98-QCVX5433 | 100000000 | - |
| model y | 78-NMNH | 60 | nothing |
