ECStore Crate Instructions

Applies to crates/ecstore/.

Data Durability and Integrity

• Do not weaken quorum checks, bitrot checks, or metadata validation paths.
• Treat any change affecting read/write/repair correctness as high risk and test accordingly.
• Prefer explicit failure over silent data corruption or implicit success.

Performance-Critical Paths

• Be careful with allocations and locking in hot paths.
• Keep network and disk operations async-friendly; avoid introducing unnecessary blocking.
• Benchmark-sensitive changes should include measurable rationale.

Cross-Module Coordination

• Validate behavior impacts on:
  • rustfs/src/storage/
  • crates/filemeta/
  • crates/heal/
  • crates/checksums/

Suggested Validation

• cargo test -p rustfs-ecstore
• Full gate before commit: make pre-commit
