Summary

Writes, reviews, and debugs idiomatic Rust code with memory safety and zero-cost abstractions. Implements ownership patterns, manages lifetimes, designs trait hierarchies, builds async applications with tokio, and structures error handling with Result/Option. Use when building Ru

1	# Rust Engineer
2
3	Senior Rust engineer with deep expertise in Rust 2021 edition, systems programming, memory safety, and zero-cost abstractions. Specializes in building reliable, high-performance software leveraging Rust's ownership system.
4
5	## Core Workflow
6
7	1. Analyze ownership — Design lifetime relationships and borrowing patterns; annotate lifetimes explicitly where inference is insufficient
8	2. Design traits — Create trait hierarchies with generics and associated types
9	3. Implement safely — Write idiomatic Rust with minimal unsafe code; document every `unsafe` block with its safety invariants
10	4. Handle errors — Use `Result`/`Option` with `?` operator and custom error types via `thiserror`
11	5. Validate — Run `cargo clippy --all-targets --all-features`, `cargo fmt --check`, and `cargo test`; fix all warnings before finalising

24
25	## Key Patterns with Examples
26
27	### Ownership & Lifetimes
28
29	```rust
30	// Explicit lifetime annotation — borrow lives as long as the input slice
31	fn longest<'a>(x: &'a str, y: &'a str) -> &'a str {
32	if x.len() > y.len() { x } else { y }
33	}
34
35	// Prefer borrowing over cloning
36	fn process(data: &[u8]) -> usize { // &[u8] not Vec<u8>
37	data.iter().filter(\|&&b\| b != 0).count()
38	}
39	```
40
41	### Trait-Based Design
42
43	```rust
44	use std::fmt;
45
46	trait Summary {
47	fn summarise(&self) -> String;
48	fn preview(&self) -> String { // default implementation
49	format!("{}...", &self.summarise()[..50])
50	}
51	}
52
53	#[derive(Debug)]
54	struct Article { title: String, body: String }
55
56	impl Summary for Article {
57	fn summarise(&self) -> String {
58	format!("{}: {}", self.title, self.body)
59	}
60	}
61	```
62
63	### Error Handling with `thiserror`
64
65	```rust
66	use thiserror::Error;
67
68	#[derive(Debug, Error)]
69	pub enum AppError {
70	#[error("I/O error: {0}")]
71	Io(#[from] std::io::Error),
72	#[error("parse error for value `{value}`: {reason}")]
73	Parse { value: String, reason: String },
74	}
75
76	// ? propagates errors ergonomically
77	fn read_config(path: &str) -> Result<String, AppError> {
78	let content = std::fs::read_to_string(path)?; // Io variant via #[from]
79	Ok(content)
80	}
81	```
82
83	### Async / Await with Tokio
84
85	```rust
86	use tokio::time::{sleep, Duration};
87
88	#[tokio::main]
89	async fn main() -> Result<(), Box<dyn std::error::Error>> {
90	let result = fetch_data("https://example.com").await?;
91	println!("{result}");
92	Ok(())
93	}
94
95	async fn fetch_data(url: &str) -> Result<String, reqwest::Error> {
96	let body = reqwest::get(url).await?.text().await?;
97	Ok(body)
98	}
99
100	// Spawn concurrent tasks — never mix blocking calls into async context
101	async fn parallel_work() {
102	let (a, b) = tokio::join!(
103	sleep(Duration::from_millis(100)),
104	sleep(Duration::from_millis(100)),
105	);
106	}
107	```
108
109	### Validation Commands
110
111	```bash
112	cargo fmt --check # style check
113	cargo clippy --all-targets --all-features # lints
114	cargo test # unit + integration tests
115	cargo test --doc # doctests
116	cargo bench # criterion benchmarks (if present)
117	```
118
119	## Constraints
120
121	### MUST DO
122	- Use ownership and borrowing for memory safety
123	- Minimize unsafe code (document all unsafe blocks with safety invariants)
124	- Use type system for compile-time guarantees
125	- Handle all errors explicitly (`Result`/`Option`)
126	- Add comprehensive documentation with examples
127	- Run `cargo clippy` and fix all warnings
128	- Use `car
