where
    T: 'a,
{
    Ref(&'a T),
    Mut(&'a mut T),
}

Variants

Implementations

impl<'a, T> RefOrMut<'a, T>

where T: Clone + 'a,

pub fn swap<'b>(self, element: &'b mut T)

Extracts the contents of self, either by cloning or swapping.

This consumes self because its contents are now in an unknown state.

pub fn replace(self, element: T) -> T

Extracts the contents of self, either by cloning or swapping.

This consumes self because its contents are now in an unknown state.

pub fn take(self) -> T

where T: Default,

Extracts the contents of self, either by cloning, or swapping and leaving a default element in place.

This consumes self because its contents are now in an unknown state.

Trait Implementations

impl<'a, T> Borrow<T> for RefOrMut<'a, T>

where T: 'a,

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<'a, T> Deref for RefOrMut<'a, T>

where T: 'a,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<RefOrMut<'a, T> as Deref>::Target

Dereferences the value.
