Enum Position 

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

The argument has a name.

Implementations

impl Position<'_>

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

Trait Implementations

impl<'input> Clone for Position<'input>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for Position<'input>

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

Formats the value using the given formatter.

impl<'input> PartialEq for Position<'input>

fn eq(&self, other: &Position<'input>) -> 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.
