Trait concurrency_traits::TryRwLock[−][src]

pub trait TryRwLock<'a> {
    type Item: ?Sized;
    type ReadGuard: Deref<Target = Self::Item>;
    type WriteGuard: DerefMut<Target = Self::Item>;
    fn try_read(&'a self) -> Option<Self::ReadGuard>;

    fn try_write(&'a self) -> Option<Self::WriteGuard>;
}

A non-blocking rwlock with try functions

Implementation

It is recommended to implement TryRwLockSized if the implement-ee can be sized.

Associated Types

type Item: ?Sized[src]

The item stored by this lock

type ReadGuard: Deref<Target = Self::Item>[src]

The guard for reading from this lock

type WriteGuard: DerefMut<Target = Self::Item>[src]

The guard for writing to this lock

Required methods

fn try_read(&'a self) -> Option<Self::ReadGuard>[src]

Tries to read from the lock, returning None if cannot immediately

fn try_write(&'a self) -> Option<Self::WriteGuard>[src]

Tries to write to the lock, returning None if not able to immediately
