pipe_macro

此crate提供了一种宏，用于像某些函数式编程语言那样管道化函数调用。

示例

fn add(a: usize, b: usize) -> usize {
    a + b
}

fn double(a: usize) -> usize {
    a * 2
}

let answer = pipe!(
    2
    => double
    => { |n| add(n, 10) }
    => double
);

assert_eq!(answer, 28);

let count = pipe!("https://rust-lang.net.cn" => download.await? => parse? => count_links);
