# Function std::fmt::format 1.0.0 [−] [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.

# Examples

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
