catch-input

一个 Rust 库，实现了从控制台获取用户输入的宏。

示例

use catch_input::input;

fn main() {
    let a = input!("PromptA => ");
    let b = input!(|| { print!("PromptB => ") });
    let c = input!((String::from("PromptC => ")));

    assert!(a, String::from("Catch"));
    assert!(b, String::from("Input"));
    assert!(c, String::from("Crate"));

    println!(">> {} : {} : {}", a, b, c);
}

$ cargo run
...

PromptA => Catch
PromptB => Input
PromptC => Crate
>> Catch : Input : Crate

lib.rs:

通过导出的 input 宏，提供一种方便获取标准输入的方法。

示例

use catch_input::input;

fn main() {
    let input_a = input!("What's your favorite food? ");
    let input_b = input!(|| { print!("What's your favorite drink? ") });
    
    assert!(input_a, String::from("Oatmeal"));
    assert!(input_b, String::from("Water"));
    
    // $ cargo run
    // What's your favorite food? Oatmeal
    // What's your favorite drink? Water
}
