pub struct FormatArguments {
    arguments: Vec<FormatArgument>,
    num_unnamed_args: usize,
    num_explicit_args: usize,
    names: FxHashMap<Symbol, usize>,
}
Expand description

The arguments to format_args!().

E.g. 1, 2, name="ferris", n=3, but also implicit captured arguments like x in format_args!("{x}").
