Concat With

While the concat! macro in std is useful to create a static string slice (&'static str) from literals, it cannot set a separator for those. This crate therefore provides another concat! macro to deal with that situation.

#[macro_use] extern crate concat_with;

assert_eq!("test10btrue", concat!("test", 10, 'b', true));
assert_eq!("test, 10, b, true", concat!(with ", ", "test", 10, 'b', true));
assert_eq!("test\n10\nb\ntrue", concat_line!("test", 10, 'b', true));
