Rust & Go Explainer

Systems languages often present steep learning curves due to unique memory models and concurrency paradigms. Study Buddy provides dedicated explainers for both Rust and Go.

🦀 Rust Explainer

Rust eliminates memory safety bugs without a garbage collector through its compile-time ownership model.

Key Analysis Features:

1. Ownership & Moves: Explains when values are moved vs. copied (Copy trait).
2. Borrowing Rules: Explains immutable references (&T) vs. mutable exclusive references (&mut T), preventing data races.
3. Lifetimes ('a): Deconstructs generic lifetime annotations and references across function returns and structs.
4. Pattern Matching & Results: Explains match, Option<T>, Result<T, E>, and the ? error propagation operator.

🐹 Go Explainer

Go is engineered for scalable network services and simple concurrency.

Key Analysis Features:

1. Goroutines & CSP Concurrency: Explains lightweight green threads started via go doWork().
2. Channels: Explains unbuffered (synchronous rendezvous) vs. buffered channels, channel direction (chan<-, <-chan), and deadlocks.
3. Select Statements: Explains non-blocking multiplexing across multiple channel communication operations.
4. Error Handling Idioms: Explains if err != nil explicit error checks and custom error types.
