Enum tract_core::internal::tract_itertools::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 for Position<T>where
    T: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

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

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

const 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<T> Copy for Position<T>where
    T: Copy,

impl<T> StructuralPartialEq for Position<T>
