# Enum itertools::EitherOrBoth

``````pub enum EitherOrBoth<A, B> {
Both(A, B),
Left(A),
Right(B),
}``````
Expand description

Value that either holds a single A or B, or both.

## Variants§

§

### Both(A, B)

Both values are present.

§

### Left(A)

Only the left value of type `A` is present.

§

### Right(B)

Only the right value of type `B` is present.

## Implementations§

source§

### impl<A, B> EitherOrBoth<A, B>

source

#### pub fn has_left(&self) -> bool

If `Left`, or `Both`, return true, otherwise, return false.

source

#### pub fn has_right(&self) -> bool

If `Right`, or `Both`, return true, otherwise, return false.

source

#### pub fn left(self) -> Option<A>

If `Left`, or `Both`, return `Some` with the left value, otherwise, return `None`.

source

#### pub fn right(self) -> Option<B>

If `Right`, or `Both`, return `Some` with the right value, otherwise, return `None`.

source

#### pub fn as_ref(&self) -> EitherOrBoth<&A, &B>

Converts from `&EitherOrBoth<A, B>` to `EitherOrBoth<&A, &B>`.

source

#### pub fn as_mut(&mut self) -> EitherOrBoth<&mut A, &mut B>

Converts from `&mut EitherOrBoth<A, B>` to `EitherOrBoth<&mut A, &mut B>`.

## Trait Implementations§

source§

### impl<A: PartialEq, B: PartialEq> PartialEq<EitherOrBoth<A, B>> for EitherOrBoth<A, B>

source§

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

This method tests for `self` and `other` values to be equal, and is used by `==`.
1.0.0 · source§

#### 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.
