Rust reference for Carbon's cargo workspace (crates/* + apps/assembler) — tokio discipline for CPU-heavy C++ FFI, ownership/interior-mutability choices, rayon isolation, error conventions, performance and profiling, all grounded in measured results from this codebase. Use when writing or reviewing Rust in this repo, deciding spawn_blocking vs inline vs rayon, picking Mutex/RwLock/DashMap/OnceLock/atomics, or hunting allocations. Do not use for the assembler's HTTP/service contract or deployment — that is apps/assembler/AGENTS.md.
