| Rule | Guideline |
| Rule | Guideline |
|---|---|
No get_ prefix | fn name() not fn get_name() |
| Iterator convention | iter() / iter_mut() / into_iter() |
| Conversion naming | as_ (cheap &), to_ (expensive), into_ (ownership) |
| Static var prefix | G_CONFIG for static, no prefix for const |
| Rule | Guideline |
|---|---|
| Use newtypes | struct Email(String) for domain semantics |
| Prefer slice patterns | if let [first, .., last] = slice |
| Pre-allocate | Vec::with_capacity(), String::with_capacity() |
| Avoid Vec abuse | Use arrays for fixed sizes |
| Rule | Guideline |
|---|---|
| Prefer bytes | s.bytes() over s.chars() when ASCII |
Use Cow<str> | When might modify borrowed data |
Use format! | Over string concatenation with + |
| Avoid nested iteration | contains() on string is O(n*m) |
| Rule | Guideline |
|---|---|
Use ? propagation | Not try!() macro |
expect() over unwrap() | When value guaranteed |
| Assertions for invariants | assert! at function entry |
| Rule | Guideline |
|---|---|
| Meaningful lifetimes | 'src, 'ctx not just 'a |
try_borrow() for RefCell | Avoid panic |
| Shadowing for transformation | let x = x.parse()? |
| Rule | Guideline |
|---|---|
| Identify lock ordering | Prevent deadlocks |
| Atomics for primitives | Not Mutex for bool/usize |
| Choose memory order carefully | Relaxed/Acquire/Release/SeqCst |
| Rule | Guideline |
|---|---|
| Sync for CPU-bound | Async is for I/O |
| Don't hold locks across await | Use scoped guards |
| Rule | Guideline |
|---|---|
| Avoid unless necessary | Prefer functions/generics |
| Follow Rust syntax | Macro input should look like Rust |
| Deprecated | Better | Since |
|---|---|---|
lazy_static! | std::sync::OnceLock | 1.70 |
once_cell::Lazy | std::sync::LazyLock | 1.80 |
std::sync::mpsc | crossbeam::channel | - |
std::sync::Mutex | parking_lot::Mutex | - |
failure/error-chain | thiserror/anyhow | - |
try!() | ? operator | 2018 |
Naming: snake_case (fn/var), CamelCase (type), SCREAMING_CASE (const)
Format: rustfmt (just use it)
Docs: /// for public items, //! for module docs
Lint: #![warn(clippy::all)]
Claude knows Rust conventions well. These are the non-obvious Rust-specific rules.
npx claudepluginhub voldemortgin/claude-skillsProvides Rust code style rules and best practices: naming conventions, error handling, memory patterns, async guidelines, and deprecated-to-modern replacements.
Guides writing idiomatic Rust code with patterns for ownership, error handling, generics dispatch, and performance. Includes clippy configuration and documentation standards.
Guides Rust best practices, common patterns, and idiomatic code for borrowing, error propagation, iterators, design patterns like builder/newtype, and &str vs &String.
