描述

Feature Request

According to https://github.com/tikv/tikv/issues/4676 in fact we have some large structures in critical paths, which may greatly impact the performance. We need to warn these large structures taken place in return values. Also it would be even better if we can check the structure size of each move!

研究方向
Investigate the referenced issue #4676 to identify specific large structures in TiKV. Explore existing Rust linting tools like clippy to see if a similar warning exists. Consider proposing a custom lint or a compile time check for large return values and moves. Look at the TiKV codebase for patterns where large structs are moved or returned, and measure their sizes.
