Rustler-detailed Rust programming guidance

Example

Explaining the use of match statements versus if let for pattern matching, accompanied by code examples.

Scenario

A user struggling with handling optional values in Rust can receive guidance on implementing match statements to cleanly handle different cases.

Example

Detailing the creation and propagation of custom error types using Rust’s error handling libraries like `thiserror` and `anyhow`.

Scenario

When a developer encounters repetitive error handling code, Rustler can suggest idiomatic Rust solutions for simplifying error propagation and handling.

Example

Illustrating the safe use of threads and data sharing with Rust's concurrency primitives such as `Arc` and `Mutex`.

Scenario

For a developer working on a high-performance web server, Rustler can explain and demonstrate how to efficiently manage state across multiple threads without running into race conditions.

Example

Providing recommendations on effective use of Rust’s zero-cost abstractions and iterator patterns for optimal performance.

Scenario

When optimizing an existing Rust application, Rustler assists by identifying inefficient code patterns and suggesting more efficient alternatives using iterators and closures.
