Trait Implementations

impl CommandEncoder for CommandEncoder

type A = Api

unsafe fn begin_encoding(&mut self, label: Label<'_>) -> Result<(), DeviceError>

Begin encoding a new command buffer.

unsafe fn end_encoding(&mut self) -> Result<CommandBuffer, DeviceError>

Return a fresh CommandBuffer holding the recorded commands.

unsafe fn discard_encoding(&mut self)

Discard the command list under construction.

unsafe fn reset_all<I>(&mut self, cmd_bufs: I)

where I: Iterator<Item = CommandBuffer>,

Reclaim all resources belonging to this CommandEncoder.

unsafe fn transition_buffers<'a, T>(&mut self, barriers: T)

where T: Iterator<Item = BufferBarrier<'a, Buffer>>,

unsafe fn transition_textures<'a, T>(&mut self, barriers: T)

where T: Iterator<Item = TextureBarrier<'a, Texture>>,

unsafe fn clear_buffer(&mut self, buffer: &Buffer, range: MemoryRange)

unsafe fn copy_buffer_to_buffer<T>( &mut self, src: &Buffer, dst: &Buffer, regions: T, )

where T: Iterator<Item = BufferCopy>,

unsafe fn copy_texture_to_texture<T>( &mut self, src: &Texture, src_usage: TextureUses, dst: &Texture, regions: T, )

where T: Iterator<Item = TextureCopy>,

Copy from one texture to another. Works with a single array layer. Note: dst current usage has to be TextureUses::COPY_DST. Note: the copy extent is in physical size (rounded to the block size)

unsafe fn copy_buffer_to_texture<T>( &mut self, src: &Buffer, dst: &Texture, regions: T, )

where T: Iterator<Item = BufferTextureCopy>,

Copy from buffer to texture. Works with a single array layer. Note: dst current usage has to be TextureUses::COPY_DST. Note: the copy extent is in physical size (rounded to the block size)

unsafe fn copy_texture_to_buffer<T>( &mut self, src: &Texture, src_usage: TextureUses, dst: &Buffer, regions: T, )

where T: Iterator<Item = BufferTextureCopy>,

Copy from texture to buffer. Works with a single array layer. Note: the copy extent is in physical size (rounded to the block size)

unsafe fn begin_query(&mut self, set: &QuerySet, index: u32)

Safety:

unsafe fn end_query(&mut self, set: &QuerySet, index: u32)

Safety:

unsafe fn write_timestamp(&mut self, set: &QuerySet, index: u32)

unsafe fn reset_queries(&mut self, set: &QuerySet, range: Range<u32>)

unsafe fn copy_query_results( &mut self, set: &QuerySet, range: Range<u32>, buffer: &Buffer, offset: BufferAddress, stride: BufferSize, )

unsafe fn build_acceleration_structures<'a, T>( &mut self, descriptor_count: u32, descriptors: T, )

where Api: 'a, T: IntoIterator<Item = BuildAccelerationStructureDescriptor<'a, Buffer, AccelerationStructure>>,

To get the required sizes for the buffer allocations use get_acceleration_structure_build_sizes per descriptor All buffers must be synchronized externally All buffer regions, which are written to may only be passed once per function call, with the exception of updates in the same descriptor. Consequences of this limitation:
