What is stack vs heap in Rust?

Stack: fixed-size, LIFO, fast push/pop. Heap: dynamic, pointer-accessed, slower but flexible.

How does Rust ownership prevent memory leaks?

Tracks heap data via unique owners—data dies with owner at scope end. No manual free.

Does Rust's ownership slow down my code?

Nope—compile-time only. Runtime matches C/C++ speeds, beats GC pauses.

Rust Ownership: Stack vs. Heap, the Real Battlefield No One Talks About

Your Rust code crashes at compile time—ownership's wrath. Stack and heap aren't abstract; they're why Rust runs circles around garbage-collected rivals.
