Heap Array (heap_arr)

The Heap Array crate is a lightweight #![no_std] library designed to facilitate the construction of arrays directly on the heap.

The provided functions within this crate enable the creation of both initialized and uninitialized arrays.

Rationale

In certain scenarios, such as attempting to create a large array using Box::new([0_u8; 1_000_000_000]), Rust defaults to creating the array on the stack before moving it to the heap. This method poses a challenge for large arrays as it can lead to stack overflow. While Rust optimizes this process in release mode by directly allocating the array on the heap, there are situations, such as frequent recompilations during testing in debug mode, where this optimization is not viable.

The Heap Array crate addresses these challenges by providing a mechanism to create arrays directly on the heap, offering a more flexible solution for scenarios where stack limitations or debugging requirements come into play.
