howto-code-in-rust SKILL.md skillA
howto-code-in-rust from ed3dai/ed3d-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when writing, reviewing, or modifying Rust code - covers error handling with thiserror+miette, type system patterns, async and serde conventions, testing crates, dependency pinning, and module organization.
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
# Writing Rust
## Overview
Rust house style. Applies whenever writing, reviewing, or modifying Rust code.
The two governing values: correctness over convenience, and pragmatic incrementalism. Use the type system aggressively to make invalid states unrepresentable, then evolve the design as patterns repeat rather than building speculative abstractions.
## Correctness over convenience
- Model the full error space. No shortcuts or simplified error handling.
- Handle all edge cases: race conditions, signal timing, platform differences.
- Use the type system to encode correctness constraints (newtypes, exhaustive matching, `#[must_use]`).
- Prefer compile-time guarantees over runtime checks where possible.
- When uncertain, explore and iterate rather than assume.
## User-facing error quality
Standard pairing: `thiserror` for structured error enums, `miette` for user-facing diagnostics with source spans, help text, and related errors. They are complementary -- `thiserror` defines the shape, `miette` adds the diagnostic layer on top.
```rust
#[derive(Debug, thiserror::Error, miette::Diagnostic)]
enum ConfigError {
#[error("failed to parse config at {path}")]

How to install
mdr add ed3dai/ed3d-plugins/howto-code-in-rust@sha256:ffd112592741751dThe line at the top of this page pins the label git:20260429.47257b5, 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.
