pub enum RefOrMut<'a, T>
where T: 'a,
{ Ref(&'a T), Mut(&'a mut T), }
Expand description

Either an immutable or mutable reference.

Variants§

§

Ref(&'a T)

An immutable reference.

§

Mut(&'a mut T)

A mutable reference.

Implementations§

source§

impl<'a, T: Clone + 'a> RefOrMut<'a, T>

source

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.

source

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.

source

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.
