Struct drone_core::heap::Pool[−][src]

pub struct Pool { /* fields omitted */ }

The set of free memory blocks.

It operates by connecting unallocated regions of memory together in a linked list, using the first word of each unallocated region as a pointer to the next.

Implementations

impl Pool[src]

pub const fn new(address: usize, size: usize, capacity: usize) -> Self[src]

Creates a new Pool.

pub fn size(&self) -> usize[src]

Returns the block size.

pub fn allocate(&self) -> Option<NonNull<u8>>[src]

Allocates one block of memory.

If this method returns Some(addr), then the addr returned will be non-null address pointing to the block. If this method returns None, then the pool is exhausted.

This operation is lock-free and has O(1) time complexity.

pub unsafe fn deallocate(&self, ptr: NonNull<u8>)[src]

Deallocates the block referenced by ptr.

This operation is lock-free and has O(1) time complexity.

Safety

  • ptr must point to a block previously allocated by alloc.
  • ptr must not be used after deallocation.
