Struct maitake::sync::spin::RwLockReadGuard

source ·
pub struct RwLockReadGuard<'lock, T>
where T: ?Sized,
{ /* private fields */ }
Expand description

An RAII implementation of a “scoped read lock” of a RwLock. When this structure is dropped (falls out of scope), the lock will be unlocked.

The data protected by the RwLock can be immutably accessed through this guard via its Deref implementation.

This structure is created by the read and try_read methods on RwLock.

Trait Implementations§

source§

source§

impl<T> Send for RwLockReadGuard<'_, T>
where T: Sync + ?Sized,

A RwLockReadGuard only allows immutable (&T) access to a T. Therefore, it is Send and Sync as long as T is Sync, because it can be used to share references to a T across multiple threads (requiring T: Sync), but it cannot be used to move ownership of a T across thread boundaries, as the T cannot be taken out of the lock through a RwLockReadGuard.
