Allows tracking state of an Action via registering IndexerExpectations on SignificantChainEvents coming from the Indexer and resolving them as they are matched. Once expectations are matched, they are automatically unregistered.

Required Methods

fn match_and_resolve<'life0, 'life1, 'async_trait>( &'life0 self, event: &'life1 SignificantChainEvent, ) -> Pin<Box<dyn Future<Output = Vec<IndexerExpectation>> + Send + 'async_trait>>

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

Tries to match the given event against the registered expectations. Each matched expectation is resolved, unregistered and returned.

fn register_expectation<'life0, 'async_trait>( &'life0 self, exp: IndexerExpectation, ) -> Pin<Box<dyn Future<Output = Result<ExpectationResolver>> + Send + 'async_trait>>

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

Registers new IndexerExpectation.

fn unregister_expectation<'life0, 'async_trait>( &'life0 self, tx_hash: Hash, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Manually unregisters IndexerExpectation given its TX hash.
