Crate concat_string [−] [src]
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")); }
