Enum tract_hir::internal::tract_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.
pub fn map_any<F, L, G, R>(self, f: F, g: G) -> EitherOrBoth<L, R> where
F: FnOnce(A) -> L,
G: FnOnce(B) -> R,
pub fn map_any<F, L, G, R>(self, f: F, g: G) -> EitherOrBoth<L, R> where
F: FnOnce(A) -> L,
G: FnOnce(B) -> R,
Apply the functions f and g on the value a and b respectively;
found in Left(a), Right(b), or Both(a, b) variants.
The Result is rewrapped self’s original variant.

pub fn left_and_then<F, L>(self, f: F) -> EitherOrBoth<L, B> where
F: FnOnce(A) -> EitherOrBoth<L, B>,
Apply the function f on the value a in Left(a) or Both(a, _) variants if it is
present.
pub fn right_and_then<F, R>(self, f: F) -> EitherOrBoth<A, R> where
F: FnOnce(B) -> EitherOrBoth<A, R>,
pub fn right_and_then<F, R>(self, f: F) -> EitherOrBoth<A, R> where
F: FnOnce(B) -> EitherOrBoth<A, R>,
Apply the function f on the value b
in Right(b) or Both(_, b) variants if it is present.
