What is Rust Option enum used for?

Handles 'value may or may not exist' without null crashes—`Some(T)` or `None`.

How does Rust Option differ from null in Java?

Option is distinct type; compiler blocks misuse. Java null hides in T, explodes at runtime.

Nope—must match or unwrap explicitly, or compile fails.

Null pointers have wrecked more codebases than you can imagine. Rust's Option enum fixes that forever—forcing you to handle 'maybe nothing' upfront.
