🔧 How to build a Heapless Vector using `MaybeUninit<T>` for Better Performance.

Finally understand MaybeUninit<T> and why it offers better performance over Option<T>, and learn to safeguard unsafe Rust with safe APIs.


TL:DR: Heapless Vector in no_std Rust.

Rust stores data on the stack (fast, fixed-size), heap (growable but needs alloc), or static (program-long); for memory-tight embedded systems, use...
