Enum Position

pub enum Position<T> {
    First(T),
    Middle(T),
    Last(T),
    Only(T),
}

A value yielded by WithPosition. Indicates the position of this element in the iterator results.

See .with_position() for more information.

Variants

First(T)

This is the first element.

Middle(T)

This is neither the first nor the last element.

Last(T)

This is the last element.

Only(T)

This is the only element.

Implementations

impl<T> Position<T>

pub fn into_inner(self) -> T

Return the inner value.

Trait Implementations

impl<T: Clone> Clone for Position<T>

fn clone(&self) -> Position<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Position<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Position<T>

fn eq(&self, other: &Position<T>) -> 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<T: Copy> Copy for Position<T>

impl<T> StructuralPartialEq for Position<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
