Trait Implementations

impl Debug for MemoryLockManager

Formats the value using the given formatter.

impl Default for MemoryLockManager

fn default() -> Self

Returns the “default value” for a type.

impl LockManager for MemoryLockManager

fn try_lock<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Option<Box<dyn LockGuard>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Try to acquire the named lock without waiting. Returns None if it is already held, the key is rejected by [validate_key], or the backend cannot acquire the lock for any other reason.

fn lock<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn LockGuard>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Acquire the named lock, polling try_lock until it succeeds or timeout elapses.
