pub struct RedisLockManager { /* private fields */ }Expand description
A LockManager that grants TTL-bounded locks via Redis SET … NX PX.
Clone-cheap: holds a cloneable ConnectionManager.
Implementations§
Source§impl RedisLockManager
impl RedisLockManager
Sourcepub fn new(conn: ConnectionManager) -> Self
pub fn new(conn: ConnectionManager) -> Self
Wrap a managed Redis connection (see cache::connect_redis).
Sourcepub async fn release_token(
&self,
key: &str,
token: LockToken,
) -> Result<bool, DataError>
pub async fn release_token( &self, key: &str, token: LockToken, ) -> Result<bool, DataError>
Release a key by fencing token, honoring the compare-and-delete so only
the still-current holder is freed. Returns true if the lock was held by
token and is now released, false if it had already expired or been
taken over.
Exposed so a process can release a lock by token without holding the
LockGuard (e.g. after recovering the token from elsewhere). The guard
returned by acquire releases through this on
release / drop.
