Struct threadcell::Guard

#[repr(transparent)]
pub struct Guard<'a, T>(_);

Expand description

Guards that a referenced ThreadCell becomes properly released when its guard becomes dropped. This covers releasing threadcells on panic. Guards do not prevent the explicit release of a ThreadCell. Deref a Guard referencing a released ThreadCell will panic!

Trait Implementations§

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

One can deref a Guard 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> Drop for Guard<'_, 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
