impl LeaseStore for MemoryLeaseStore

fn claim<'life0, 'async_trait>( &'life0 self, lease: ConsumerLease, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Claim a shard lease for an instance (fails if held by another live member).

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Renew all leases held by an instance in the group.

fn release<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, group_id: &'life1 str, instance_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Release all leases held by an instance in the group.
