# Struct std::fmt::Arguments 1.0.0 [−] [src]

    pub struct Arguments<'a> { /* fields omitted */ }

This structure represents a safely precompiled version of a format string and its arguments. This cannot be generated at runtime because it cannot safely be done, so no constructors are given and the fields are private to prevent modification.

The `format_args!` macro will safely create an instance of this structure and pass it to a function or closure, passed as the first argument. The macro validates the format string at compile-time so usage of the `write` and `format` functions can be safely performed.

## 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`)
