Enum rustc_parse_format::Position

pub enum Position {
    ArgumentImplicitlyIs(usize),
    ArgumentIs(usize),
    ArgumentNamed(Symbol),
}

Enum describing where an argument for a format can be located.

Variants

ArgumentImplicitlyIs(usize)

Tuple Fields

0: usize

The argument is implied to be located at an index

ArgumentIs(usize)

Tuple Fields

0: usize

The argument is located at a specific index given in the format

ArgumentNamed(Symbol)

Tuple Fields

0: Symbol

The argument has a name.

Implementations

impl Position

pub fn index(&self) -> Option<usize>

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl PartialEq<Position> for Position

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

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

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

This method tests for !=.

impl Copy for Position

impl StructuralPartialEq for Position

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.
