unsafe

MaybeUninit<T> is the safe way to work with uninitialized memory. It's useful for FFI, performance-critical code, or when you need to initialize large arrays element-by-element. Unlike uninitialized variables (which are UB), MaybeUninit is expli

Unsafe Rust lets you bypass some of the compiler's safety checks when necessary. Common uses include FFI (calling C code), dereferencing raw pointers, and implementing low-level data structures. The unsafe keyword creates a boundary where you promise

Rust's inline assembly (asm! macro) lets you write assembly for performance-critical code or to access hardware features. It's an unstable feature (nightly only) and requires unsafe. I use it sparingly for SIMD intrinsics not exposed by std::arch, cry
