Struct SharedLock 

pub struct SharedLock<T>(/* private fields */);

Thread-safe shared mutable value using Mutex for exclusive access.

Implementations

impl<T> SharedLock<T>

pub fn new(v: T) -> Self

Create a new shared value.

pub fn with<F, R>(&self, f: F) -> Result<R, PoisonError<MutexGuard<'_, T>>>

where F: FnOnce(&mut T) -> R,

Execute a closure with mutable access to the inner value.

Caution: f runs while the mutex is held. Avoid re-entering this SharedLock from inside the closure.

pub fn get(&self) -> Result<T, PoisonError<MutexGuard<'_, T>>>

where T: Clone,

Get a cloned snapshot of the value.

pub fn set(&self, value: T) -> Result<(), PoisonError<MutexGuard<'_, T>>>

Replace the inner value.

Trait Implementations

impl<T> Clone for SharedLock<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for SharedLock<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
