Module services

Services

This module regroups services. Services are adapters in charge of the different bounded contexts of the application:

• Aggregator Client: communicate with the Aggregator
• Cardano Transactions: handle Cardano transactions (import, preload, etc.)
• Single Signer: create single signatures
• Upkeep: perform maintenance tasks

Each service is defined by a public API (a trait) that is used in the controllers (runtimes).

Structs

• AggregatorHTTPClient
  AggregatorHTTPClient is a http client for an aggregator
• CardanoTransactionsImporter
  Import and store CardanoTransaction.
• CardanoTransactionsPreloaderActivationSigner
  CardanoTransactionsPreloaderActivationSigner
• MithrilEpochService
  Implementation of the epoch service.
• MithrilProtocolInitializerBuilder
  This is responsible for creating new instances of ProtocolInitializer.
• MithrilSingleSigner
  Implementation of the SingleSigner.
• SignerCertifierService
  Implementation of the Certifier Service for the Mithril Signer.
• SignerSignableSeedBuilder
  SignableSeedBuilder signer implementation
• SignerSignedEntityConfigProvider
  Simple wrapper to the EpochService to implement the SignedEntityConfigProvider trait.
• SignerUpkeepService
  Implementation of the upkeep service for the signer.
• TransactionsImporterByChunk
  A decorator of TransactionsImporter that does the import by chunks
• TransactionsImporterWithPruner
  A decorator of TransactionsImporter that prunes the transactions older than a given number of blocks after running the import.
• TransactionsImporterWithVacuum
  A decorator of TransactionsImporter that vacuums the database after running the import.

Enums
