GuardMut

Struct GuardMut

pub struct GuardMut<'a, T>(/* private fields */);

Expand description

Mutable Guard that ensures that a referenced ThreadCell becomes properly released when it becomes dropped. Guards do not prevent the explicit release of a ThreadCell. Deref a GuardMut referencing a released ThreadCell will panic!

Trait Implementations§

impl<T> Deref for GuardMut<'_, T>

One can deref a GuardMut as long the ThreadCell is owned by the current thread this should be the case as long the guarded ThreadCell got not explicitly released or stolen.

§Panics

When the underlying ThreadCell is not owned by the current thread.

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for GuardMut<'_, T>

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

Mutably dereferences the value.

impl<T> Drop for GuardMut<'_, T>

Releases the referenced ThreadCell when it is owned by the current thread.

fn drop(&mut self)

Executes the destructor for this type. Read more
