The format function takes a precompiled format string and a list of arguments, to return the resulting formatted string.

Arguments

• args - a structure of arguments generated via the format_args! macro. Because this structure can only be safely generated at compile-time, this function is safe.

Example

use std::fmt;

let s = format_args!(fmt::format, "Hello, {}!", "world");
assert_eq!(s, ~"Hello, world!");
