Rust Performance

This skill is about measurement-first optimization in Rust.

If the task is primarily code style, ownership, or API design, use rust-patterns first.

When to activate

• Investigating latency, throughput, CPU, memory, or allocation regressions in Rust
• Benchmarking a hot path before and after a change
• Hunting down lock contention, slow async pipelines, or poor data layout
• Tuning release profiles or deciding whether parallelism actually helps
