impl<'a, T> IntoIterator for &'a OneOrMany<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = IntoIter<<&'a OneOrMany<T> as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a OneOrMany<T> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<T> IntoIterator for OneOrMany<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<<OneOrMany<T> as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <OneOrMany<T> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<T> Ord for OneOrMany<T>

where T: Ord,

fn cmp(&self, other: &OneOrMany<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T> PartialEq for OneOrMany<T>

where T: PartialEq,

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

Tests for self and other values to be equal, and is used by ==.

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