# std::format_args! [−] [src]

    macro_rules! format_args {
        ($fmt:expr, $($args:tt)*) => { ... };
    }

The core macro for formatted string creation & output.

This macro produces a value of type `fmt::Arguments`. This value can be passed to the functions in `std::fmt` for performing useful functions. All other formatting macros (`format!`, `write!`, `println!`, etc) are proxied through this one.

For more information, see the documentation in `std::fmt`.

# Examples

fn main() { use std::fmt; let s = fmt::format(format_args!("hello {}", "world")); assert_eq!(s, format!("hello {}", "world")); }

    use std::fmt;

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

## 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`)
