rust-async-patterns SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
rust-async-patterns from rudycity/superagent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rudycity/superagent/rust-async-patterns@git:20260626.019dba9Pins git:20260626.019dba9 in mdr.lock. Pin the fingerprint instead.

Master Rust async programming with Tokio, async traits, error handling, and concurrent patterns. Use when building async Rust applications, implementing concurrent systems, or debugging async code.
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 Async Patterns
Production patterns for async Rust programming with Tokio runtime, including tasks, channels, streams, and error handling.
## When to Use This Skill
- Building async Rust applications
- Implementing concurrent network services
- Using Tokio for async I/O
- Handling async errors properly
- Debugging async code issues
- Optimizing async performance
## Core Concepts
### 1. Async Execution Model
```
Future (lazy) → poll() → Ready(value) | Pending
↑ ↓
Waker ← Runtime schedules
```
### 2. Key Abstractions
| Concept | Purpose |
| ---------- | ---------------------------------------- |
| `Future` | Lazy computation that may complete later |
| `async fn` | Function returning impl Future |
| `await` | Suspend until future completes |
| `Task` | Spawned future running concurrently |
| `Runtime` | Executor that polls futures |
## Quick Start
```toml
# Cargo.toml
[dependencies]
tokio = { version = "1", features = ["full"] }
futures = "0.3"
async-trait = "0.1"
anyhow = "1.0"
tracing = "0.1"
tracing-subscriber = "0.3"
```
```rust

How to install
mdr add rudycity/superagent/rust-async-patterns@sha256:8e9a951c21bb1ee6The line at the top of this page pins the label git:20260626.019dba9, 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.
