Struct shared_mutex::MappedSharedMutexWriteGuard
[−]
[src]
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>[src]
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.
