Struct InMemoryLockManager 

Source 
pub struct InMemoryLockManager { /* private fields */ }
Expand description

A thread-safe, in-memory LockManager for tests and single-process use.

Expiry is evaluated against an injected Clock, so a FixedClock makes TTL behavior deterministic in tests.

Implementations§

Source§

impl InMemoryLockManager

Source

pub fn new(clock: Arc<dyn Clock>) -> Self

A manager driven by clock (use a FixedClock in tests).

Trait Implementations§
