# 1.0.0[−][src]Macro std::concat

    macro_rules! concat {
        ($ ($ e : expr), *) => { ... };
        ($ ($ e : expr,) *) => { ... };
    }

Concatenates literals into a static string slice.

This macro takes any number of comma-separated literals, yielding an expression of type `&'static str` which represents all of the literals concatenated left-to-right.

Integer and floating point literals are stringified in order to be concatenated.

# Examples

    let s = concat!("test", 10, 'b', true);
    assert_eq!(s, "test10btrue");Run
