Higher-kinded types in Rust allow abstraction over type constructors, enhancing generic programming. Though not natively supported, the community simulates HKTs using clever techniques, enabling powerful abstractions without runtime overhead.
Rust emphasizes safety and security. Best practices include updating toolchains, careful memory management, minimal unsafe code, proper error handling, input validation, using established cryptography libraries, and regular dependency audits.
Rust's borrow checker ensures safe memory management in complex data structures. It enforces ownership rules, preventing data races and null pointer dereferences. Techniques like using indices and interior mutability help navigate challenges in implementing linked lists and graphs.
