Struct Queue 

pub struct Queue { /* private fields */ }

Implementations

impl Queue

pub fn submit(&self, command_buffer: CommandBuffer) -> Result<(), Error>

Submits a CommandBuffer to the GPU queue and waits synchronously for execution to finish.

Example

use lgpu::{CommandBuffer, Queue};

queue.submit(cmd).expect("GPU submission failed");

pub fn submit_surface_work( &self, command_buffer: CommandBuffer, surface_texture: &SurfaceTexture, ) -> Result<(), Error>

Submits command buffer work targeted to a swapchain surface without presenting. The acquired surface can then be presented explicitly via SurfaceTexture::present.

pub fn submit_surface( &self, command_buffer: CommandBuffer, surface_texture: SurfaceTexture, ) -> Result<(), Error>

Submits command buffer work targeted to a swapchain surface and immediately queues presentation.

pub fn submit_batches( &self, command_buffers: Vec<CommandBuffer>, ) -> Result<(), Error>

pub fn submit_async( &self, command_buffer: CommandBuffer, wait_semaphores: &[(&TimelineSemaphore, u64)], signal_semaphores: &[(&TimelineSemaphore, u64)], ) -> Result<(), Error>

pub fn submit_batches_async( &self, command_buffers: Vec<CommandBuffer>, wait_semaphores: &[(&TimelineSemaphore, u64)], signal_semaphores: &[(&TimelineSemaphore, u64)], ) -> Result<(), Error>

pub fn write_texture(&self, texture: &Texture, data: &[u8]) -> Result<(), Error>

pub fn write_buffer( &self, buffer: &Buffer, offset: u64, data: &[u8], ) -> Result<(), Error>

Writes byte data into a host-mapped Buffer at the specified offset.

Example

use lgpu::{Buffer, Queue};

queue.write_buffer(buffer, 0, &[1u8, 2, 3, 4]).expect("Failed to write buffer");
