Struct MongoLockManager 

pub struct MongoLockManager { /* private fields */ }

A LockManager that stores TTL-bounded locks in a MongoDB collection.

Clone-cheap: holds only the collection handle (an Arc internally).

Implementations

impl MongoLockManager

pub fn new(db: &Database) -> Self

Wrap an existing database, using the default collection name "locks".

pub fn with_collection(db: &Database, collection_name: &str) -> Self

Wrap an existing database, using collection_name as the target.

pub async fn release_token( &self, key: &str, token: LockToken, ) -> Result<bool, DataError>

Release key only if token still owns it.

Returns true if the lock was held and is now released, false if it had already expired or been taken by a different holder.

Trait Implementations

impl Clone for MongoLockManager

fn clone(&self) -> MongoLockManager

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl LockManager for MongoLockManager

fn acquire<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<Option<LockGuard>, DataError>> + Send + 'async_trait>>

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

Try to acquire key for ttl. Returns Some(guard) if the lock was free (or held by an expired acquisition), or None if a live holder owns it.
