Structs

• Block0
  Block0 representation
• BlockBuilder
  Block builder responsible for building blocks
• CardanoWallet
  Represents Cardano mainnet wallet which is able to generate registration transaction metadata
• InMemoryDbSync
  Mock of real cardano db sync. At this moment we only stores transactions metadata as the only purpose of existance for this struct is to provide catalyst voting registrations Struct can be persisted and restored from json file using serde_json.
• InMemoryNode
  In memory cardano node implementation. Basic design contains read write lock over ledger struct as well as background task for updating ledger
• Initials
  Root struct for defining snapshot template
• Ledger
  Simulates cardano node behavior. Contains mempool of transactions as well as blockchain. Meant to be used as library in current thread.
• METADATUM_1
  metadatum label 1 constant
• METADATUM_2
  metadatum label 2 constant
• METADATUM_3
  metadatum label 3 constant
• METADATUM_4
  metadatum label 4 constant
• MainnetNetworkBuilder
  Cardano Network state builder, responsible to create a given state of cardano network which will be an input for snapshot
• REGISTRATION_METADATA_IDX
  registration metadata index constant
• REGISTRATION_METADATA_LABEL
  registration metadata constant
• REGISTRATION_METADATA_SIGNATURE_LABEL
  registration signature metadata constant
• REGISTRATION_SIGNATURE_METADATA_IDX
  registration signature metadata index constant
• RegistrationTransactionBuilder
  Responsible for building registration transaction metadata
• Settings
  Cardano node mock settings
• SharedInMemoryDbSync
  thread safe InMemoryDbSync. It has inner struct db_sync with rw lock guard and handle to update thread which listen to InMemoryNode mock block updates
• SnapshotParameters
  Snapshot
• TransactionBuilder
  Transaction builder for cardano mainnet

Enums

• DbSyncError
  Db sync error
• JsonConversionError
  Metadata conversion error

Constants

• CARDANO_MAINNET_SLOTS_PER_EPOCH
  Const defining caradno mainnet slot per epoch setting

Traits

• BlockDateFromCardanoAbsoluteSlotNo
  Basic converter from absolute slot number and {epoch,slot} pair
• GeneralTransactionMetadataInfo
  Extension for GeneralTransactionMetadata tailored for Catalyst purposes
