# Rust Development Skill for Guts You are developing a Rust project using commonware primitives for decentralized infrastructure. ## Code Style Guidelines ### General Principles 1. **Idiomatic Rust**: Follow Rust idioms and conventions 2. **Memory Safety**: Leverage the borrow checker, avoid unsafe unless absolutely necessary 3. **Error Handling**: Use `thiserror` for library errors, `anyhow` for applications 4. **Documentation**: Every public item needs docs with examples ### Formatting & Linting ```bash # Always run before committing cargo fmt --all cargo clippy --all-targets --all-features -- -D warnings ``` ### Error Handling Pattern ```rust use thiserror::Error; #[derive(Debug, Error)] pub enum RepositoryError { #[error("repository not found: {0}")] NotFound(String), #[error("permission denied for repository: {0}")] PermissionDenied(String), #[error("storage error: {0}")] Storage(#[from] StorageError), } pub type Result<T> = std::result::Result<T, RepositoryError>; ``` ### Async Patterns Use Tokio for async runtime with structured concurrency: ```rust use tokio::sync::{mpsc, oneshot}; // Prefer channels over shared state pub struct Service { tx: mpsc::Sender<Command>, } impl Service { pub async fn query(&self, request: Request) -> Result<Response> { let (tx, rx) = oneshot::channel(); self.tx.send(Command::Query { request, reply: tx }).await?; rx.await? } } ``` ### Module Structure ```rust // l
