Enum otter::imports::itertools::EitherOrBoth [−][src]
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 values are present.
Only the left value of type A
is present.
Only the right value of type B
is present.
Implementations
If Left, return true otherwise, return false.
Exclusive version of [has_left
].
If Right, return true otherwise, return false.
Exclusive version of [has_right
].
If Right, return true otherwise, return false.
Equivalent to self.as_ref().both().is_some()
.
If Left
, or Both
, return Some
with the left value, otherwise, return None
.
If Right
, or Both
, return Some
with the right value, otherwise, return None
.
Converts from &EitherOrBoth<A, B>
to EitherOrBoth<&A, &B>
.
Converts from &mut EitherOrBoth<A, B>
to EitherOrBoth<&mut A, &mut B>
.
Convert EitherOrBoth<A, B>
to EitherOrBoth<B, A>
.
Apply the function f
on the value a
in Left(a)
or Both(a, b)
variants. If it is
present rewrapping the result in self
’s original variant.
Apply the function f
on the value b
in Right(b)
or Both(a, b)
variants.
If it is present rewrapping the result in self
’s original variant.
