In Rust, null pointer dereferences, also known as null pointer errors or null reference errors, refer to situations where a program attempts to access or dereference a null or uninitialized pointer. However, Rust's ownership and borrowing system and its lack of null pointers make null pointer dereferences virtually non-existent. Rust's approach to null safety revolves around the concept of ownership and borrowing, which eliminates the need for null pointers and effectively prevents null pointer dereferences at compile-time. Instead of allowing null values, Rust uses the `Option` type to represent the presence or absence of a value. The `Option` type is an enum with two variants: `Some(value)` to represent the presence of a value, and `None` to represent the absence of a value. By using `Option` types, Rust enforces explicit handling of potentially missing values, ensuring that developers handle the absence case explicitly, rather than encountering unexpected null pointer der...
