Implementations

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

pub fn is_left(&self) -> bool

Returns whether it is Left variant or not.

impl<A> Either<A, A>

pub fn into(self) -> A

Works only if they are of the same type.

Trait Implementations

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

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

Formats the value using the given formatter.

impl<A, B> Future for Either<A, B>

where A: Future + Unpin, B: Future<Output = A::Output> + Unpin,

type Output = <A as Future>::Output

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, ctx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
