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(A, B)

Both values are present.

§

Left(A)

Only the left value of type A is present.

§

Right(B)

Only the right value of type B is present.

Implementations§

source§

impl<A, B> EitherOrBoth<A, B>

source

pub fn has_left(&self) -> bool

If Left, or Both, return true, otherwise, return false.

source

pub fn has_right(&self) -> bool

If Right, or Both, return true, otherwise, return false.

source

pub fn left(self) -> Option<A>

If Left, or Both, return Some with the left value, otherwise, return None.

source

pub fn right(self) -> Option<B>

If Right, or Both, return Some with the right value, otherwise, return None.

source

pub fn as_ref(&self) -> EitherOrBoth<&A, &B>

Converts from &EitherOrBoth<A, B> to EitherOrBoth<&A, &B>.

source

pub fn as_mut(&mut self) -> EitherOrBoth<&mut A, &mut B>
