Function std::fmt::format1.0.0 [] [src]

pub fn format(args: Arguments) -> String

The format function takes an Arguments struct and returns the resulting formatted string.

The Arguments instance can be created with the format_args! macro.


Basic usage:

use std::fmt;

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

Please note that using format! might be preferable. Example:

let s = format!("Hello, {}!", "world");
assert_eq!(s, "Hello, world!");Run
