Required methods

fn kind() -> Kind

Get allocator kind.

fn alloc(
    &mut self,
    device: &<B as Backend>::Device,
    size: u64,
    align: u64
) -> Result<(Self::Block, u64), AllocationError>

Allocate block of memory. On success returns allocated block and amount of memory consumed from device.

fn free(&mut self, device: &<B as Backend>::Device, block: Self::Block) -> u64

Free block of memory. Returns amount of memory returned to the device.
