disp

为实现了Debug的类型派生Display

示例

mod hello {
    use std::fmt::Display;

    #[derive(Debug, disp::Display)]
    pub struct Hello {}
}

fn main() {
    let hello = hello::Hello {};
    println!("Debug: {hello:?}, world!");
    println!("Display: {hello}, world!");
}

输出

Debug: Hello, world!
Display: Hello, world!
