Enum Either3 

pub enum Either3<A, B, C> {
    First(A),
    Second(B),
    Third(C),
}

Result type for select3 - represents which of three futures completed first.

Variants

First(A)

First future completed first

Second(B)

Second future completed first

Third(C)

Third future completed first

Implementations

impl<A, B, C> Either3<A, B, C>

pub fn index(&self) -> usize

Returns the index of the winner (0 for First, 1 for Second, 2 for Third)

impl<T> Either3<T, T, T>

pub fn into_tuple(self) -> (usize, T)

For homogeneous Either3 (all types are the same), extract as (index, value).

Trait Implementations

impl<A: Clone, B: Clone, C: Clone> Clone for Either3<A, B, C>

fn clone(&self) -> Either3<A, B, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug, B: Debug, C: Debug> Debug for Either3<A, B, C>

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

Formats the value using the given formatter.

impl<A: PartialEq, B: PartialEq, C: PartialEq> PartialEq for Either3<A, B, C>

fn eq(&self, other: &Either3<A, B, C>) -> 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.
