Macro to_string

macro_rules! macro to_string

Sometimes I get tired typing in to_string, especially in test cases so I wrote this macro.


macro_rules! s(($result:expr) => ($result.to_string()));

fn main() {
    let name = s!("Foo Bar");
    println!("Hello, {}!", name);

I am a bit ambivalent as I don't like one-letter variables or functions name, but I want this to be short.

An besides I can search for s! if I am looking for all the uses.
