#![warn(clippy::pedantic)]| Pattern | Usage | Example |
|---|---|---|
as_* | Cheap reference-to-reference conversion | as_str(), as_bytes() |
to_* | Expensive conversion, creates new value | to_string(), to_vec() |
into_* | Consumes self, returns different type | into_inner(), into_bytes() |
from_* | Associated function constructor | from_str(), from_parts() |
try_* | Fallible version of another function | try_from(), try_lock() |
with_* | Builder-pattern setter | with_capacity(), with_timeout() |
is_* / has_* | Boolean query | is_empty(), has_key() |
Do NOT use get_ prefix — use bare name: fn name(&self) -> &str not fn get_name().

Activates for async/await, tokio, futures, Send/Sync traits, Arc/Mutex usage, channels, thread pools, parallelism with rayon, and concurrent data structure questions.
Rust error handling patterns and strategies. Activates for Result/Option usage, custom error types, error propagation with ?, anyhow/thiserror usage, panic handling, and error type design questions.
Rust ownership, borrowing, and lifetimes specialist. Activates on move errors (E0382, E0505, E0507, E0515), lifetime errors (E0597, E0716, E0106), borrow checker issues, and questions about ownership semantics, Clone vs Copy, and reference lifetimes.
Rust project architecture and design. Use for project structure decisions, workspace organization, module hierarchy, crate splitting, dependency injection, and trait-based design. Invoke with /rust-architecture for architecture reviews.
Rust CI/CD setup and release automation. Activates for GitHub Actions configuration, clippy/rustfmt CI, release workflows, cross-compilation, and deployment questions. Invoke with /rust-ci.
Rust dependency management and Cargo.toml configuration. Activates for dependency selection, feature flags, version management, workspace dependencies, publishing, and Cargo.toml questions.
