Module eth_bridge::requests

Modules

• encode_packed

Structs

• Encoder
• EthPeersSync
  A helper structure used to add or remove peer on Ethereum network.
• IncomingAddToken
  Incoming request for adding Sidechain token to a bridge.
• IncomingCancelOutgoingRequest
  Incoming request for cancelling a obsolete outgoing request. “Obsolete” means that the request signatures were collected, but something changed in the bridge state (e.g., peers set) and the signatures became invalid. In this case we want to cancel the request to be able to re-submit it later.
• IncomingChangePeers
  Incoming request for adding/removing peer in a bridge.
• IncomingChangePeersCompat
• IncomingMarkAsDoneRequest
  Incoming request that’s used to mark outgoing requests as done. Since off-chain workers query Sidechain networks lazily, we should force them to check if some outgoing request was finalized on Sidechain.
• IncomingMigrate
  Incoming request that acts as an acknowledgement to a corresponding OutgoingMigrate request.
• IncomingPrepareForMigration
  Incoming request that acts as an acknowledgement to a corresponding OutgoingPrepareForMigration request.
• IncomingTransfer
  Incoming request for transferring token from Sidechain to Thischain.
• LoadIncomingMetaRequest
  Information needed for a request to be loaded from sidechain. Basically it’s a hash of the transaction and the type of the request.
• LoadIncomingTransactionRequest
  Information needed for a request to be loaded from sidechain. Basically it’s a hash of the transaction and the type of the request.
• OutgoingAddAsset
  Outgoing request for adding a Thischain asset.
• OutgoingAddAssetEncoded
  Sidechain-compatible version of OutgoingAddAsset.
• OutgoingAddPeer
  Outgoing request for adding a peer.
• OutgoingAddPeerCompat
  Old contracts-compatible add peer request. Will be removed in the future.
• OutgoingAddPeerEncoded
  Sidechain-compatible version of OutgoingAddPeer.
• OutgoingAddToken
  Outgoing request for adding a Sidechain token.
• OutgoingAddTokenEncoded
  Sidechain-compatible version of OutgoingAddToken.
• OutgoingMigrate
  Outgoing request for migrating the bridge. For the full migration process description see OutgoingPrepareForMigration request.
• OutgoingMigrateEncoded
  Sidechain-compatible version of OutgoingMigrate.
• OutgoingPrepareForMigration
  Outgoing request for preparing bridge for migration.
• OutgoingPrepareForMigrationEncoded
  Sidechain-compatible version of OutgoingPrepareForMigration.
• OutgoingRemovePeer
  Outgoing request for removing a peer.
• OutgoingRemovePeerCompat
  Old contracts-compatible add peer request. Will be removed in the future.
• OutgoingRemovePeerEncoded
  Sidechain-compatible version of OutgoingRemovePeer.
• OutgoingTransfer
  Outgoing request for transferring the given asset from Thischain to Sidechain.
• OutgoingTransferEncoded
  Sidechain-compatible version of OutgoingTransfer.

Enums

• AssetKind
  A type of asset registered on a bridge.
• ChangePeersContract
• CurrencyIdEncoded
  Thischain or Sidechain asset id.
• IncomingMetaRequestKind
  Types of meta-requests that can be made.
• IncomingRequest
  Incoming (Sidechain->Thischain) request.
• IncomingRequestKind
  Types of requests that can be made from a sidechain.
• IncomingTransactionRequestKind
  Types of transaction-requests that can be made from a sidechain.
• LoadIncomingRequest
• OffchainRequest
  A bridge operation handled by off-chain workers.
• OutgoingRequest
  Outgoing (Thischain->Sidechain) request.
• OutgoingRequestEncoded
  Ethereum-encoded OutgoingRequest. Contains a payload for signing by peers. Also, can be used by client apps for more convenient contract function calls.
• RequestStatus
  Status of a registered request.

Constants

• MAX_PEERS
• MIN_PEERS

Functions

• encode_outgoing_request_eth_call
  Encodes the given outgoing request as it should look when it gets called on Sidechain.
• parse_hash_from_call
  Parses a tx_hash argument of a contract call. tx_hash is usually a hash of a Thischain’s outgoing request (OutgoingRequest).
• signature_params_to_tokens
  Converts signature params to Sidechain-compatible tokens.
