Struct len_caching_lock::mutex::LenCachingMutex

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

Can be used in place of a Mutex where reading T’s len() without needing to lock, is advantageous. When the Guard is released, T’s len() will be cached. The cached len() may be at most 1 lock behind current state.

Implementations

impl<T: Len> LenCachingMutex<T>

pub fn new(data: T) -> Self

Constructs a new LenCachingMutex

impl<T: Len + ?Sized> LenCachingMutex<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 lock(&self) -> CachingMutexGuard<'_, T>

Delegates to parking_lot::Mutex lock().

pub fn try_lock(&self) -> Option<CachingMutexGuard<'_, T>>

Delegates to parking_lot::Mutex try_lock().
