Crate dynalock

Dynalock: A lease based distributed lock.

Dynalock algorithm supports lease based distributed locking implementations through providers that support a strongly consistent Compare-And-Swap (CAS) operation, or at least the compare-and-set variant and an eventually consistent read operation. For algorithmic details please refer to the README.md file.

You can use this library to cooperatively synchronize access on a conceptual resource (e.g., pushing an item to a queue). The main data structure we use to describe the lock is DistLock.

The generic structure DistLock accepts a single type parameter Driver to delegate the implementation of the Locking trait to back-end or storage driver implementations. As an example, the DynamoDB driver implements the Locking trait for DistLock<DynamoDbDriver>. The Locking trait is an API contract where driver implementations will implement the Dynalock algorithm for using the provider's primitives.
