Enum mod_utilities::Either

pub enum Either<A, B> {
    A(A),
    B(B),
}

A wrapper for a value that is either one type or another

Similar to Result, but without the semantic connotations

Variants

A(A)

B(B)

Implementations

impl<A, B> Either<A, B>

Trait Implementations

impl<A: Clone, B: Clone> Clone for Either<A, B>

fn clone(&self) -> Either<A, B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Copy, B: Copy> Copy for Either<A, B>

impl<A: Debug, B: Debug> Debug for Either<A, B>

Formats the value using the given formatter.

impl<A: Eq, B: Eq> Eq for Either<A, B>

impl<A: Ord, B: Ord> Ord for Either<A, B>

fn cmp(&self, other: &Either<A, B>) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<A: PartialEq, B: PartialEq> PartialEq<Either<A, B>> for Either<A, B>

fn eq(&self, other: &Either<A, B>) -> bool

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

fn ne(&self, other: &Either<A, B>) -> bool

This method tests for !=.

impl<A: PartialOrd, B: PartialOrd> PartialOrd<Either<A, B>> for Either<A, B>

fn partial_cmp(&self, other: &Either<A, B>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Either<A, B>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Either<A, B>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Either<A, B>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Either<A, B>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
