Trait Implementations

impl<F1: Clone, F2: Clone> Clone for OneTwo<F1, F2>

fn clone(&self) -> OneTwo<F1, F2>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F1: Debug, F2: Debug> Debug for OneTwo<F1, F2>

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

Formats the value using the given formatter.

impl<T1, E1, F1, T2, E2, F2> FusedFuture for OneTwo<F1, F2>

where F1: Future<Output = Result<T1, E1>>, F2: Future<Output = Result<T2, E2>>, E2: From<E1>,

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<T1, E1, F1, T2, E2, F2> Future for OneTwo<F1, F2>

where F1: Future<Output = Result<T1, E1>>, F2: Future<Output = Result<T2, E2>>, E2: From<E1>,

type Output = Result<T2, E2>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &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.

impl<F1: Hash, F2: Hash> Hash for OneTwo<F1, F2>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<F1: Ord, F2: Ord> Ord for OneTwo<F1, F2>

fn cmp(&self, other: &OneTwo<F1, F2>) -> 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,

Restrict a value to a certain interval.

impl<F1: PartialEq, F2: PartialEq> PartialEq for OneTwo<F1, F2>

fn eq(&self, other: &OneTwo<F1, F2>) -> 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.

impl<F1: PartialOrd, F2: PartialOrd> PartialOrd for OneTwo<F1, F2>

fn partial_cmp(&self, other: &OneTwo<F1, F2>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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