Enum clippy_utils::macros::Count

source ·

pub enum Count<'tcx> {
    Is(usize, Span),
    Param(FormatParam<'tcx>),
    Implied,
}

Expand description

Used by width and precision specifiers.

Variants

`Is(usize, Span)`

Specified with a literal number, stores the value.

`Param(FormatParam<'tcx>)`

Specified using $ and * syntaxes. The * format is still considered to be FormatParamKind::Numbered.

`Implied`

Not specified.
