Rust programming language coding conventions and best practices

# Rust Coding Conventions and Best Practices

Follow idiomatic Rust practices and community standards when writing Rust code. 

These instructions are based on [The Rust Book](https://doc.rust-lang.org/book/), [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/), [RFC 430 naming conventions](https://github.com/rust-lang/rfcs/blob/master/text/0430-finalizing-naming-conventions.md), and the broader Rust community at [users.rust-lang.org](https://users.rust-lang.org).

## General Instructions

- Always prioritize readability, safety, and maintainability.
- Use strong typing and leverage Rust's ownership system for memory safety.
- Break down complex functions into smaller, more manageable functions.
- For algorithm-related code, include explanations of the approach used.
- Write code with good maintainability practices, including comments on why certain design decisions were made.
- Handle errors gracefully using `Result<T, E>` and provide meaningful error messages.
- For external dependencies, mention their usage and purpose in documentation.
- Use consistent naming conventions following [RFC 430](https://github.com/rust-lang/rfcs/blob/master/text/0430-finalizing-naming-conventions.md).
- Write idiomatic, safe, and efficient Rust code that follows the borrow checker's rules.
- Ensure code compiles without warnings.

## Patterns to Follow

- Use modules (`mod`) and public interfaces (`pub`) to encapsulate logic.
- Handle errors properly using `?`, `match`, or `if let`.
- Use `serde` for serialization and `thiserror` or `anyhow` for custom errors.
- Implement traits to abstract services or external dependencies.
