Struct len_caching_lock::rwlock::LenCachingRwLock

pub struct LenCachingRwLock<T: ?Sized> { /* fields omitted */ }

Can be used in place of a RwLock where reading T’s len() without needing to lock, is advantageous. When the WriteGuard is released, T’s len() will be cached.

Implementations

impl<T: Len> LenCachingRwLock<T>

pub fn new(data: T) -> Self

Constructs a new LenCachingRwLock

impl<T: Len + ?Sized> LenCachingRwLock<T>

pub fn load_len(&self) -> usize

Load the cached value that was returned from your T’s len() subsequent to the most recent lock being released.

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

Delegates to parking_lot::RwLock write().

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

Delegates to parking_lot::RwLock try_write().

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

Delegates to parking_lot::RwLock read().

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

Delegates to parking_lot::RwLock try_read().
