[−][src]Struct basic_allocator::allocators::RawAlloc

pub struct RawAlloc<G> {
    pub grower: G,
    pub blocks: BlockList,
}

A raw allocator, capable of growing the heap, returning pointers to new allocations, and tracking and reusing freed memory.

Note: It never returns memory to the OS; that is not implemented.

This roughly corresponds to the AllocRef trait in Rust nightly, but does not directly implement that trait (although it probably could... TODO!)

Fields

grower: Gblocks: BlockList

Implementations

impl<G: HeapGrower> RawAlloc<G>[src]

pub fn new(grower: G) -> Self[src]

Create a new RawAlloc

pub fn stats(&self) -> (Validity, Stats)[src]

Get statistics on this allocator, and verify validity of the BlockList

pub fn block_size(layout: Layout) -> usize[src]

Calculate the minimum size of a block to be allocated for the given layout.

pub unsafe fn alloc(&mut self, layout: Layout) -> *mut u8[src]

Allocate space for something fitting in layout

Safety

This is very unsafe. See GlobalAlloc for details.

pub unsafe fn dealloc(&mut self, ptr: *mut u8, layout: Layout)[src]

Deallocate (or "free") a memory block.

Safety

This is very unsafe. See GlobalAlloc for details.
