Macro heap_bitmap

macro_rules! heap_bitmap {
    (chunks=$chunk_amount:path) => { ... };
    (chunks=$chunk_amount:literal) => { ... };
    () => { ... };
}

Helper macro that initializes a page-aligned static memory area with a correct size to get used as heap bookkeeping bitmap in crate::GlobalChunkAllocator.

Example

use simple_chunk_allocator::heap_bitmap;

// chunk size: 256; chunk amount: 16
let heap_bitmap = heap_bitmap!(chunks = 16);

const CHUNK_AMOUNT: usize = 24;
let heap_bitmap = heap_bitmap!(chunks = CHUNK_AMOUNT);
