Walkthrough

The PR refactors FromStr trait implementations for EthAddress and EthHash by switching from manual implementations to derived implementations using derive_more::FromStr. Error handling in EthTraceTransaction is enhanced with contextual error messaging for invalid transaction hashes.

Changes

Cohort / File(s)	Summary
FromStr derivation src/rpc/methods/eth/types.rs	Added FromStr derive macro from derive_more for both EthAddress and EthHash; removed manual impl FromStr for EthAddress
FromStr cleanup src/rpc/methods/eth.rs	Removed impl FromStr for EthHash block; updated EthTraceTransaction to wrap string parsing with .context("invalid transaction hash") for improved error reporting
