Struct RwLockBellWriteGuard 

pub struct RwLockBellWriteGuard<'a, T> { /* private fields */ }

RAII write guard for RwLockBell.

Provides exclusive write access via Deref and DerefMut. Dropping releases the lock and fires every callback registered via try_write_or while this guard was held.

Returned by RwLockBell::write, RwLockBell::try_write, and RwLockBell::try_write_or.

Implementations

impl<'a, T> RwLockBellWriteGuard<'a, T>

pub fn map<U, F>(self, f: F) -> MappedRwLockBellWriteGuard<'a, U>

where F: FnOnce(&mut T) -> &mut U,

Maps this guard to a subfield of the protected value.

pub fn try_map<U, F>( self, f: F, ) -> Result<MappedRwLockBellWriteGuard<'a, U>, Self>

where F: FnOnce(&mut T) -> Option<&mut U>,

Maps this guard to a subfield, returning Err(self) if f returns None.

pub fn try_map_err<U, F, E>( self, f: F, ) -> Result<MappedRwLockBellWriteGuard<'a, U>, (Self, E)>

where F: FnOnce(&mut T) -> Result<&mut U, E>,

Maps this guard to a subfield, returning Err((self, e)) if f returns Err(e).

Trait Implementations

impl<'a, T: Debug> Debug for RwLockBellWriteGuard<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> Deref for RwLockBellWriteGuard<'a, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a, T> DerefMut for RwLockBellWriteGuard<'a, T>

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

Mutably dereferences the value.

impl<'a, T> Drop for RwLockBellWriteGuard<'a, T>

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.
