Enum ChunkAllocatorError

pub enum ChunkAllocatorError {
    BadHeapMemory,
    BadBitmapMemory,
    BadChunkSize,
    OutOfMemory,
}

Possible errors of ChunkAllocator.

Variants

BadHeapMemory

The backing memory for the heap must be

• not empty
• an multiple of the used chunk size that is a multiple of 8, and
• not start at 0
• be aligned to the chunk size.

BadBitmapMemory

The number of bits in the backing memory for the heap bitmap must match the number of chunks in the heap.

BadChunkSize

The chunk size must be not 0 and a power of 2.

OutOfMemory

The heap is either completely full or to fragmented to serve the request. Also, it may happen that the alignment can’t get guaranteed, because all aligned chunks are already in use.
