Methods

impl BufferPlan

pub fn coherent(&mut self) -> &mut BufferPlan

Create COHERENT buffer, if supported by the driver.

pub fn cached(&mut self) -> &mut BufferPlan

Create CPU_CACHED buffer, if supported by the driver.

pub fn device_local(&mut self) -> &mut BufferPlan

Create DEVICE_LOCAL buffer, if supported by the driver.

pub fn cpu_visible(&mut self) -> &mut BufferPlan

Require a buffer to be CPU_VISIBLE.

pub fn permanent(&mut self) -> &mut BufferPlan

Hint the allocator that the buffer will live for a long time.

By default, allocator assumes the buffer is a short-lived object.

pub fn create<B: Backend>(
    &self,
    factory: &mut Factory<B>
) -> Fallible<Buffer<B>>

Build the buffer, allocating the memory and binding it to the buffer.
