Struct RwLock 

pub struct RwLock<T> { /* private fields */ }

Reader-writer lock owning a T. See module docs for semantics.

Implementations

impl<T> RwLock<T>

pub const fn new(value: T) -> Self

Const-init. Parity with parking_lot::RwLock::new / parking_lot::const_rwlock.

pub fn read(&self) -> RwLockReadGuard<'_, T>

Acquire a shared read lock, blocking if a writer holds (or is waiting for) the lock.

pub fn write(&self) -> RwLockWriteGuard<'_, T>

Acquire an exclusive write lock, blocking until all readers and any other writer have released.

pub fn try_read(&self) -> Option<RwLockReadGuard<'_, T>>

Non-blocking read.

pub fn try_write(&self) -> Option<RwLockWriteGuard<'_, T>>

Non-blocking write.

pub fn get_mut(&mut self) -> &mut T

Lock-free mutable access via &mut self (exclusive borrow proves no other thread holds the lock). Parity with parking_lot::RwLock::get_mut.

pub fn into_inner(self) -> T

Consume the lock, returning the inner value.
