Struct sp_runtime::offchain::storage_lock::StorageLockGuard [−][src]
pub struct StorageLockGuard<'a, 'b, L: Lockable> { /* fields omitted */ }
RAII style guard for a lock.
Implementations
impl<'a, 'b, L: Lockable> StorageLockGuard<'a, 'b, L>[src]
impl<'a, 'b, L: Lockable> StorageLockGuard<'a, 'b, L>[src]pub fn forget(self)[src]
Consume the guard but do not unlock the underlying lock.
Can be used to implement a grace period after doing some heavy computations and sending a transaction to be included on-chain. By forgetting the lock, it will stay locked until its expiration deadline is reached while the off-chain worker can already exit.
pub fn extend_lock(&mut self) -> Result<<L as Lockable>::Deadline, ()>[src]
Extend the lock by guard deadline if it already exists.
i.e. large sets of items for which it is hard to calculate a meaning full conservative deadline which does not block for a very long time on node termination.
