Struct Queue 

pub struct Queue { /* private fields */ }

the device’s queue

Implementations

impl Queue

pub fn submit<'a, I: IntoIterator<Item = CommandBuffer<'a>>>( &self, cmds: I, ) -> Result<SubmitId>

run command buffers in order -> their number

pub fn flush(&self) -> Result<SubmitId>

nothing waits for a submission here

pub fn write_buffer<T: Pod>( &self, buf: &Buffer, offset: u64, data: &[T], ) -> Result<()>

write data into a buffer at offset, before the next submission

pub fn write_texture( &self, dst: &TextureRegion<'_>, data: &[u8], layout: DataLayout, _before: Layout, _after: Layout, ) -> Result<()>

write texels into a texture region, before the next submission (no layouts here)

pub fn write_texture_rects( &self, t: &Texture, rects: &[[i32; 4]], data: &[u8], stride: u32, before: Layout, after: Layout, ) -> Result<()>

write rectangles (x, y, w, h; clipped to the texture, empty ones skipped) of mip 0, layer 0 from data, an image of the texture’s size in rows of stride bytes (a framebuffer)

pub fn write_texture_rects_at( &self, t: &Texture, rects: &[[i32; 4]], origin: (i32, i32), data: &[u8], stride: u32, _before: Layout, _after: Layout, ) -> Result<()>

write_texture_rects from an image of another size: rectangles of data go to (x - origin.0, y - origin.1) of the texture; what lies outside the image or the texture is skipped

pub fn read_buffer<T: Pod>( &self, _buf: &Buffer, _offset: u64, _out: &mut [T], ) -> Result<()>

the worker cannot wait for the GPU: a Readback buffer and Buffer::read

Trait Implementations

impl Clone for Queue

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
