Struct allocators::freelist::FreeList

pub struct FreeList<'a, A: 'a + Allocator> {
    // some fields omitted
}

A FreeList allocator manages a list of free memory blocks of uniform size. Whenever a block is requested, it returns the first free block.

Methods

impl FreeList<'static, HeapAllocator>

fn new(block_size: usize, num_blocks: usize) -> Result<Self, Error>

Creates a new FreeList backed by the heap. block_size must be greater than or equal to the size of a pointer.

impl<'a, A: 'a + Allocator> FreeList<'a, A>

fn new_from(alloc: &'a A, block_size: usize, num_blocks: usize) -> Result<Self, Error>

Creates a new FreeList backed by another allocator. block_size must be greater than or equal to the size of a pointer.
