rust-async-patterns skillA
rust-async-patterns is agent-read markdown (skill) from dicklesworthstone/pi_agent_rust: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 dicklesworthstone/pi_agent_rust/rust-async-patterns@git:20260205.788be98mdr add dicklesworthstone/pi_agent_rust/rust-async-patterns@sha256:ffc91349c31b69c4Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
