Rust is considered a memory-safe programming language due to its strict ownership model and extensive compile-time checks. Here are some key features of Rust that contribute to its memory safety:

1. Ownership and Borrowing: Rust enforces strict rules for ownership and borrowing, which help prevent common memory-related bugs such as use-after-free, double-free, and data races. Each value in Rust has a single owner, and ownership can be transferred or borrowed through references. This enables the compiler to track and enforce memory safety guarantees at compile time.

2. Ownership Transfer: Rust's ownership model ensures that there is always one owner for a particular resource, and when ownership is transferred, the previous owner no longer has access to it. This eliminates the possibility of multiple entities modifying the same memory concurrently, preventing data races.

3. Borrowing and Lifetimes: Rust uses a concept called lifetimes to ensure that borrowed references are always valid and do not outlive the data they reference. The compiler analyzes the lifetimes of references and enforces strict rules to prevent dangling or invalid references, which can lead to memory safety issues.

4. Zero-cost Abstractions: Rust provides high-level abstractions without sacrificing performance. It achieves this by enforcing memory safety at compile time through static analysis, without requiring runtime checks. This means that the memory safety guarantees come with no runtime overhead.

5. Compiler Checks and Safety Guarantees: The Rust compiler performs extensive static analysis on the code to catch potential memory safety issues, such as null pointer dereferences and buffer overflows, during compilation. This prevents many common memory-related bugs from occurring in the first place.

By combining these features, Rust offers memory safety without sacrificing performance, making it suitable for systems programming where low-level control and reliability are essential.
