Concatenates literals into a static string slice.

This macro is like the concat! macro in std, but can also be used to concatenate literals separated by a specific literal. Prefixes and suffixes can also be added.

#[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));
