Struct TempRef 

pub struct TempRef<'a, T, F: FnMut(&mut T)> { /* private fields */ }

A mutable reference wrapper from Temp<T, F>.

When dropped, it automatically calls the reset function on the underlying value. This ensures that temporary mutations never leave the value in an inconsistent state.

Implementations

impl<'a, T, F: FnMut(&mut T)> TempRef<'a, T, F>

pub fn reset(&mut self)

Invokes the reset function on the internal value.

Trait Implementations

impl<'a, T, F: FnMut(&mut T)> Deref for TempRef<'a, T, F>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, T, F: FnMut(&mut T)> DerefMut for TempRef<'a, T, F>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'a, T, F: FnMut(&mut T)> Drop for TempRef<'a, T, F>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
