Wraps a buffer.

Implementations§

Source§

impl<LT: Lifetime> Buffer<LT>

Source

pub fn raw(&self) -> Buffer

The raw Vulkan buffer handle.

Source

pub unsafe fn mapped_slice(&self) -> Result<Option<&[u8]>, AscheError>

Returns a valid mapped slice if the buffer memory is host visible, otherwise it will return None.

Source

pub unsafe fn mapped_slice_mut( &mut self, ) -> Result<Option<&mut [u8]>, AscheError>

Returns a valid mapped mutable slice if the buffer memory is host visible, otherwise it will return None.

Source

pub unsafe fn flush(&self) -> Result<(), AscheError>

Flush the mapped memory of the buffer. Used for CPU->GPU transfers. Vulkan Manual Page

Source

pub unsafe fn invalidate(&self) -> Result<(), AscheError>

Invalidate the mapped memory of the buffer. Used for GPU->CPU transfers. Vulkan Manual Page

Source

pub unsafe fn device_address(&self) -> DeviceAddress

Query an address of a buffer. Vulkan Manual Page
