7. How Does Rust Handle Memory Management in Game Development?

Rust’s memory management is one of its standout features, offering a unique approach that combines performance with safety. Rust achieves memory safety through its ownership and borrowing system, which prevents common bugs like null pointer dereferences and data races at compile time.

Ownership: Every value in Rust has a single owner, which is responsible for freeing the memory when the value is no longer needed.
Borrowing: Multiple immutable references (borrows) to a value can exist simultaneously, but only one mutable reference is allowed at a time.
Lifetimes: Lifetimes ensure that references do not outlive the data they point to, preventing dangling pointers.
Move Semantics: When ownership is transferred, the original variable is invalidated, preventing double frees.

This system allows Rust to manage memory automatically without relying on garbage collection, resulting in high performance and predictable behavior.

8. What Tools and Libraries are Available for Rust Game Developers?
