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}")
.
