Struct parking_method::Recursive
source · [−]pub struct Recursive<T>(pub T);Expand description
Marker for recursive locking. Allows to obtain a read-lock multiple times by a single thread.
Panics
There are no try_write_recursive forms in parking_lot. Trying to call this will panic.

sourcefn read(&self, rwlock: &'a RwLock<V>) -> Option<RwLockReadGuard<'a, V>>
fn read(&self, rwlock: &'a RwLock<V>) -> Option<RwLockReadGuard<'a, V>>
Obtain a read lock. Blocking locks are infallible and always return a ‘Some()’ variant.
sourcefn write(&self, rwlock: &'a RwLock<V>) -> Option<RwLockWriteGuard<'a, V>>
fn write(&self, rwlock: &'a RwLock<V>) -> Option<RwLockWriteGuard<'a, V>>
Obtain a write lock. Blocking locks are infallible and always return a ‘Some()’ variant.
