Struct WriteGuard 

pub struct WriteGuard<'lock, T, U = T> { /* private fields */ }

A RAII guard that guarantees unique write access to a TryRwLock.

Implementations

impl<'lock, T, U> WriteGuard<'lock, T, U>

pub fn rwlock(guard: &Self) -> &'lock TryRwLock<T>

Get a shared reference to the lock that this write guard has locked.

pub fn downgrade(guard: Self) -> ReadGuard<'lock, T>

Downgrade the WriteGuard to a ReadGuard.

Note that for soundness reasons, this will undo any maping that has previously been applied.

pub fn map<V>( guard: Self, f: impl FnOnce(&mut U) -> &mut V, ) -> WriteGuard<'lock, T, V>

Map to another value and keep locked.

pub fn unmap(guard: Self) -> WriteGuard<'lock, T>

Undo any previous mapping applied, returning the guard back to its original state.
