Function std::fmt::format
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.
Examples
Basic usage:
use std::fmt;
let s = fmt::format(format_args!("Hello, {}!", "world"));
assert_eq!(s, "Hello, world!");
Please note that using format!
might be preferable. Example:
let s = format!("Hello, {}!", "world");
assert_eq!(s, "Hello, world!");
