Struct rustc_data_structures::sync::freeze::FreezeWriteGuard

pub struct FreezeWriteGuard<'a, T: ?Sized> {
    _lock_guard: WriteGuard<'a, ()>,
    frozen: &'a AtomicBool,
    data: NonNull<T>,
    marker: PhantomData<&'a mut T>,
}

A guard holding mutable access to a FreezeLock which is in a locked state or frozen.

Fields

_lock_guard: WriteGuard<'a, ()>

frozen: &'a AtomicBool

data: NonNull<T>

marker: PhantomData<&'a mut T>

Implementations

impl<'a, T> FreezeWriteGuard<'a, T>

pub fn freeze(self) -> &'a T

impl<'a, T: ?Sized> FreezeWriteGuard<'a, T>

pub fn map<U: ?Sized>( this: Self, f: impl FnOnce(&mut T) -> &mut U ) -> FreezeWriteGuard<'a, U>

Trait Implementations

impl<'a, T: ?Sized + 'a> Deref for FreezeWriteGuard<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T: ?Sized + 'a> DerefMut for FreezeWriteGuard<'a, T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
