Enum rustc_parse_format::Count

pub enum Count {
    CountIs(usize),
    CountIsName(Symbol),
    CountIsParam(usize),
    CountImplied,
}

A count is used for the precision and width parameters of an integer, and can reference either an argument or a literal integer.

Variants

CountIs

The count is specified explicitly.

Tuple Fields of CountIs

0: usize

CountIsName

The count is specified by the argument with the given name.

Tuple Fields of CountIsName

0: Symbol

CountIsParam

The count is specified by the argument at the given index.

Tuple Fields of CountIsParam

0: usize

CountImplied

The count is implied and cannot be explicitly specified.

Trait Implementations

impl Clone for Count

fn clone(&self) -> Count

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Count

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

Formats the value using the given formatter.

impl PartialEq<Count> for Count

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Copy for Count

impl StructuralPartialEq for Count

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
