Trait Allocator 

pub trait Allocator<B: Backend> {
    type Block: Block<B>;

    const KIND: Kind;

    // Required methods
    fn alloc(
        &mut self,
        device: &B::Device,
        size: Size,
        align: Size,
    ) -> Result<(Self::Block, Size), AllocationError>;
    fn free(&mut self, device: &B::Device, block: Self::Block) -> Size;
}

Allocator trait implemented for various allocators.

Required Associated Constants

const KIND: Kind

Allocator kind.

Required Associated Types

type Block: Block<B>

Block type returned by allocator.

Required Methods

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

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

fn free(&mut self, device: &B::Device, block: Self::Block) -> Size

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
