Crate concat_string

Macros for concatenating string slices into owned strings.

This crate provides the concat_string! macro for efficiently concatenating string slices into owned strings. concat_string! accepts any number of arguments that implement AsRef<str> and creates a String with the appropriate capacity, without the need for format strings and their associated runtime overhead.

Example

#[macro_use(concat_string)]
extern crate concat_string;

fn main() {
    println!("{}", concat_string!("Hello", String::from(" "), "world"));
}
