Struct ContractEventHandlers

Source 
pub struct ContractEventHandlers<T, Db> { /* private fields */ }
Expand description

Event handling an object for on-chain operations

Once an on-chain operation is recorded by the crate::block::Indexer, it is pre-processed and passed on to this object that handles event-specific actions for each on-chain operation.

Implementations§

Source§

impl<T, Db> ContractEventHandlers<T, Db>
where T: HoprIndexerRpcOperations + Clone + Send + 'static, Db: HoprDbAllOperations + Clone,

Source

pub fn new( addresses: ContractAddresses, safe_address: Address, chain_key: ChainKeypair, db: Db, rpc_operations: T, ) -> Self

Creates a new instance of contract event handlers with RPC operations support.

This constructor initializes the event handlers with all necessary dependencies for processing blockchain events and making direct RPC calls for fresh state data.

§Type Parameters
  • T - Type implementing HoprIndexerRpcOperations for blockchain queries
§Arguments
  • addresses - Contract addresses configuration
  • safe_address - The node’s safe address for filtering relevant events
  • chain_key - Cryptographic key for chain operations
  • db - Database connection for persistent storage
  • rpc_operations - RPC interface for direct blockchain queries
§Returns
  • Self - New instance of ContractEventHandlers
