Struct ContractUpdateIndexer 

pub struct ContractUpdateIndexer {
    pub target_address: ContractAddress,
    pub entrypoint: OwnedEntrypointName,
}

An indexer that retrieves smart contract updates where the specific entrypoint of a contract was triggered as the top-level entrypoint.

The on_connect and on_failure methods of the Indexer trait only log the events on info and warn levels, respectively, using the tracing crate. The target of the log is ccd_indexer which may be used to filter the logs.

Fields

target_address: ContractAddress

entrypoint: OwnedEntrypointName

Trait Implementations

impl Indexer for ContractUpdateIndexer

type Context = ()

The data that is retrieved upon connecting to the endpoint and supplied to each call of on_finalized.

type Data = (BlockInfo, Vec<ContractUpdateInfo>)

The data returned by the on_finalized call.

fn on_connect<'a, 'life0, 'async_trait>( &'life0 mut self, endpoint: Endpoint, _client: &'a mut Client, ) -> Pin<Box<dyn Future<Output = QueryResult<()>> + Send + 'async_trait>>

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

Called when a new connection is established to the given endpoint. The return value from this method is passed to each call of on_finalized.

fn on_finalized<'a, 'life0, 'async_trait>( &'life0 self, client: Client, _ctx: &'a (), fbi: FinalizedBlockInfo, ) -> Pin<Box<dyn Future<Output = OnFinalizationResult<Self::Data>> + Send + 'async_trait>>

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

The main method of this trait. It is called for each finalized block that the indexer discovers. Note that the indexer might call this concurrently for multiple blocks at the same time to speed up indexing.

fn on_failure<'life0, 'async_trait>( &'life0 mut self, endpoint: Endpoint, successive_failures: u64, err: TraverseError, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Called when either connecting to the node or querying the node fails. The number of successive failures without progress is passed to the method which should return whether to stop indexing (true) or not (false).
