Struct shared_mutex::MappedSharedMutexWriteGuard

pub struct MappedSharedMutexWriteGuard<'mutex, T: ?Sized + 'mutex> {
    // some fields omitted
}

A write guard to a sub-borrow of an original SharedMutexWriteGuard.

Unlike SharedMutexWriteGuard, it cannot be used to wait on a Condvar.

Methods

impl<'mutex, T: ?Sized> MappedSharedMutexWriteGuard<'mutex, T>

fn map<U, F>(self, action: F) -> MappedSharedMutexWriteGuard<'mutex, U> where F: FnOnce(&mut T) -> &mut U

Transform this guard into a sub-borrow of the original data.

fn option_map<U, F>(self, action: F) -> Option<MappedSharedMutexWriteGuard<'mutex, U>> where F: FnOnce(&mut T) -> Option<&mut U>

Conditionally transform this guard into a sub-borrow of the original data.

fn result_map<U, E, F>(self, action: F) -> Result<MappedSharedMutexWriteGuard<'mutex, U>, (Self, E)> where F: FnOnce(&mut T) -> Result<&mut U, E>

Conditionally transform this guard into a sub-borrow of the original data.

If the transformation operation is aborted, returns the original guard.

fn recover<U: ?Sized>(self, mutex: &'mutex SharedMutex<U>) -> Result<SharedMutexWriteGuard<'mutex, U>, Self>

Recover the original guard for waiting.

Takes the original mutex to recover the original type and data. If the passed mutex is not the same object as the original mutex, returns Err.
