Macro constcat::concat

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

Concatenate const &str expressions and literals into a static string slice.

This macro takes any number of comma-separated literals or constant expressions and yields an expression of type &'static str which represents all of the literals and expressions concatenated left-to-right. Integer, floating point, and boolean literals are stringified in order to be concatenated. Finally, each expression is converted to a byte slice and concatenated using concat_slices!.

See the crate documentation for examples.
