rust-patterns SKILL.md skillA
rust-patterns from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add affaan-m/ecc/rust-patterns@git:20260607.4ad5756Pins git:20260607.4ad5756 in mdr.lock. Pin the fingerprint instead.

Idiomatic Rust patterns, ownership, error handling, traits, concurrency, and best practices for building safe, performant applications.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rust Development Patterns
Idiomatic Rust patterns and best practices for building safe, performant, and maintainable applications.
## When to Use
- Writing new Rust code
- Reviewing Rust code
- Refactoring existing Rust code
- Designing crate structure and module layout
## How It Works
This skill enforces idiomatic Rust conventions across six key areas: ownership and borrowing to prevent data races at compile time, `Result`/`?` error propagation with `thiserror` for libraries and `anyhow` for applications, enums and exhaustive pattern matching to make illegal states unrepresentable, traits and generics for zero-cost abstraction, safe concurrency via `Arc<Mutex<T>>`, channels, and async/await, and minimal `pub` surfaces organized by domain.
## Core Principles
### 1. Ownership and Borrowing
Rust's ownership system prevents data races and memory bugs at compile time.
```rust
// Good: Pass references when you don't need ownership
fn process(data: &[u8]) -> usize {
data.len()
}
// Good: Take ownership only when you need to store or consume
fn store(data: Vec<u8>) -> Record {
Record { payload: data }
}
// Bad: Cloning unnecessarily to avoid borrow checker

How to install
mdr add affaan-m/ecc/rust-patterns@sha256:6d50dc50f21e033bThe line at the top of this page pins the label git:20260607.4ad5756, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
