An abstraction for acquiring and releasing distributed locks.

Required Methods

fn acquire<'life0, 'life1, 'async_trait>( &'life0 self, resource_key: &'life1 str, options: LockOptions, ) -> Pin<Box<dyn Future<Output = Result<Guard, DistributedError>> + Send + 'async_trait>>

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

Attempt to acquire a distributed lock on a resource.

fn release<'life0, 'async_trait>( &'life0 self, guard: Guard, ) -> Pin<Box<dyn Future<Output = Result<(), DistributedError>> + Send + 'async_trait>>

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

Release the acquired lock.

fn extend<'life0, 'life1, 'async_trait>( &'life0 self, guard: &'life1 Guard, additional_ttl_ms: u64, ) -> Pin<Box<dyn Future<Output = Result<(), DistributedError>> + Send + 'async_trait>>

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

Extend the TTL of the currently held lock.
