Struct maitake_sync::OwnedRwLockReadGuard

pub struct OwnedRwLockReadGuard<T: ?Sized> { /* private fields */ }
Available on crate feature alloc only.
Expand description

Owned RAII structure used to release the shared read access of a RwLock when dropped.

This type is similar to the RwLockReadGuard type, but it is only returned by an RwLock that is wrapped in an an Arc. Instead of borrowing the RwLock, this guard holds an Arc clone of the RwLock, incrementing its reference count. Therefore, this type can outlive the RwLock that created it, and it is valid for the 'static lifetime. Beyond this, it is identical to the RwLockReadGuard type.

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

This guard can be held across any .await point, as it implements Send.

This structure is created by the read_owned and try_read_owned methods on Arc<RwLock>.
