Rust Polyglot Conventions

Edition 2024: let-chains, gen blocks, if/match guards. Naming: PascalCase (types), snake_case (fns/vars/modules), SCREAMING_SNAKE_CASE (consts).

Error handling: Result<T, Error>, never .unwrap() in production, use ?, IO errors bubble up properly, SAFETY comments for unsafe code, handle lock poisoning.

Async: Tokio throughout, #[tokio::main]/#[tokio::test], provide _sync wrappers, never std::thread::sleep.

Memory: Arc for shared ownership, Mutex/RwLock for interior mutability, streaming for large data, RAII patterns.

Performance: ahash for HashMap, lazy_static/once_cell, SIMD where appropriate, zero-copy (&str/&[u8]).

Plugins: Traits for extensibility, Arc<dyn Trait> storage, Send+Sync requirements, registry pattern.

Zero clippy warnings (cargo clippy -- -D warnings).

Core structure: Modular organization with trait-based extensibility. Plugin flow: Input→Registry→Handler→Pipeline→Output.
