Enum rustc_builtin_macros::format_foreign::printf::Num

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

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.

Implementations

impl Num

fn from_str(s: &str, arg: Option<&str>) -> Option<Self>

fn translate(&self, s: &mut String) -> Result

Trait Implementations

impl Clone for Num

fn clone(&self) -> Num

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Num

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Num

fn eq(&self, other: &Num) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Num

impl StructuralPartialEq for Num

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
