Store contract used by runtime lease supervisors.

Required Associated Types

type Error: Display + Send + Sync + 'static

Store error type.

Required Methods

fn try_acquire<'life0, 'life1, 'async_trait>( &'life0 self, claim: RuntimeLeaseClaim<'life1>, ) -> Pin<Box<dyn Future<Output = Result<RuntimeLeaseAcquire, Self::Error>> + Send + 'async_trait>>

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

Attempts to acquire the lease for the caller.

fn renew<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, lease_id: &'life1 str, owner_id: &'life2 str, now: DateTime<Utc>, expires_at: DateTime<Utc>, ) -> Pin<Box<dyn Future<Output = Result<bool, Self::Error>> + Send + 'async_trait>>

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

Renews an owned lease and returns whether ownership was still held.

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

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

Releases an owned lease during cooperative shutdown.
