Enum rustc_parse_format::Position

pub enum Position<'a> {
    ArgumentImplicitlyIs(usize),
    ArgumentIs(usize),
    ArgumentNamed(&'a str),
}

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

Variants

ArgumentImplicitlyIs(usize)

The argument is implied to be located at an index

ArgumentIs(usize)

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

ArgumentNamed(&'a str)

The argument has a name.

Implementations

impl Position<'_>

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

Trait Implementations

impl<'a> Clone for Position<'a>

fn clone(&self) -> Position<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Position<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq<Position<'a>> for Position<'a>

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

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

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

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

impl<'a> Copy for Position<'a>

impl<'a> StructuralPartialEq for Position<'a>

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.
