Crate hopr_chain_rpc

Expand description

This crate contains types and traits that ensure correct interfacing with Ethereum RPC providers.

The most important trait is HoprRpcOperations which allows to send arbitrary on-chain transactions and also to perform the selection of HOPR-related smart contract operations. Secondly, the HoprIndexerRpcOperations is a trait that contains all operations required by the Indexer to subscribe to the block with logs from the chain.

Both of these traits implemented and realized via the RpcOperations type, so this represents the main entry point to all RPC related operations.

Modules§

client: Extended JsonRpcClient abstraction.
errors
indexer: Extends the RpcOperations type with functionality needed by the Indexer component.
rpc: General purpose high-level RPC operations implementation (HoprRpcOperations).

Structs§

BlockWithLogs: Structure containing filtered logs that all belong to the same block.
HttpPostRequestorConfig: Common configuration for all native HttpPostRequestors
Log: A type containing selected fields from the eth_getLogs RPC calls.
LogFilter: Represents a filter to extract logs containing specific contract events from a block.
NodeSafeModuleStatus: Represents the on-chain status for the Node Safe module.
PendingTransaction: Represents a pending transaction that can be eventually resolved until confirmation, which is done by polling the respective RPC provider.
TransactionReceipt: Contains some selected fields of a receipt for a transaction that has been already included in the blockchain.
ZeroRetryPolicy: Performs no retries.

Enums§

RetryAction: Indicates what retry action should be taken, as result of a RetryPolicy implementation.
TypedTransaction: The TypedTransaction enum represents all Ethereum transaction types.

Traits§

HoprIndexerRpcOperations: Trait with RPC provider functionality required by the Indexer.
HoprRpcOperations: Trait defining a general set of operations an RPC provider must provide to the HOPR node.
HttpPostRequestor: Abstraction for an HTTP client that performs HTTP POST with serializable request data.
RetryPolicy: Simple retry policy trait
