Struct len_caching_lock::rwlock::LenCachingRwLock

source · [−]

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

Expand description

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

source

impl<T: Len> LenCachingRwLock<T>

source

pub fn new(data: T) -> Self

Constructs a new LenCachingRwLock

source

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

source

pub fn load_len(&self) -> usize

source

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

Delegates to parking_lot::RwLock write().

source
