std::stringify

Macro std::stringify

macro_rules! stringify {
    ($t:tt) => { ... };
}

A macro which stringifies its argument.

This macro will yield an expression of type &'static str which is the stringification of all the tokens passed to the macro. No restrictions are placed on the syntax of the macro invocation itself.

Note that the expanded results of the input tokens may change in the future. You should be careful if you rely on the output.

Examples

let one_plus_one = stringify!(1 + 1);
assert_eq!(one_plus_one, "1 + 1");
