描述

Feature Request

There is a missing piece in https://github.com/tikv/tikv/pull/5979 that we recently extracted a new crate called txn_types where basic txn structures relies on. Thus it need to reduce error size as well.

研究方向
Refer to PR #5979 for the extraction of the txn types crate. The goal is to reduce the size of error types within that crate, similar to reductions done in the main crate. Examine the error enum definitions in txn types, likely in files like `src/error.rs` or similar. Identify any large variants that can be boxed or otherwise shrunk. Look at the existing error patterns in the main TiKV codebase for guidance.
