pub struct LockGuard { /* private fields */ }Expand description
A guard that represents an acquired distributed lock.
The lock is automatically released when this guard is dropped. This ensures
the lock is released regardless of how the protected code exits (normal return,
early return via ?, or panic).
The release is performed via a spawned task to avoid blocking in Drop.
If you need to confirm the release succeeded, call release() explicitly instead.
§Drop Behavior
When dropped, the guard spawns an async task to release the lock. This is best-effort: if the task fails (e.g., Redis unavailable), the lock will still expire after TTL.
Implementations§
Source§impl LockGuard
impl LockGuard
Sourcepub async fn release(self) -> Result<bool>
pub async fn release(self) -> Result<bool>
Explicitly releases the lock before TTL expiry.
This uses a Lua script to ensure we only delete the lock if we still own it. This prevents accidentally releasing a lock that was already expired and re-acquired by another instance.
Calling this method consumes the guard and prevents the Drop-based release.
§Returns
Ok(true)- Lock was successfully releasedOk(false)- Lock was not released (already expired or owned by another instance)Err(_)- Redis communication error
