1.6.0

Use the `format!` syntax to write data into a buffer.

This macro is typically used with a buffer of `&mut` `Write`.

See `std::fmt` for more information on format syntax.

# Examples

fn main() { use std::io::Write; let mut w = Vec::new(); write!(&mut w, "test").unwrap(); write!(&mut w, "formatted {}", "arguments").unwrap(); assert_eq!(w, b"testformatted arguments"); }

    use std::io::Write;

    let mut w = Vec::new();
    write!(&mut w, "test").unwrap();
    write!(&mut w, "formatted {}", "arguments").unwrap();

    assert_eq!(w, b"testformatted arguments");

## 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`)
