Enum rustc_builtin_macros::format_foreign::printf::Num

source · [−]

pub enum Num {
    Num(u16),
    Arg(u16),
    Next,
}

Expand description

A general number used in a printf formatting directive.

Variants

`Num(u16)`

A specific, fixed value.

`Arg(u16)`

The value is derived from a positional argument.

`Next`

The value is derived from the “next” unconverted argument.
