}

Encoder for commands in command buffers. Serves as a parent for all the encoded command buffers. Works in bursts of action: one or more command buffers are recorded, then submitted to a queue, and then it needs to be reset_all().

Required Methods

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

Begin encoding a new command buffer.

unsafe fn discard_encoding(&mut self)

Discard currently recorded list, if any.

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

unsafe fn reset_all<I>(&mut self, command_buffers: I)where I: Iterator<Item = A::CommandBuffer>,

Reclaims all resources that are allocated for this encoder. Must get all of the produced command buffers back, and they must not be used by GPU at this moment.

unsafe fn transition_buffers<'a, T>(&mut self, barriers: T)where T: Iterator<Item = BufferBarrier<'a, A>>,

unsafe fn transition_textures<'a, T>(&mut self, barriers: T)where T: Iterator<Item = TextureBarrier<'a, A>>,

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

unsafe fn copy_buffer_to_buffer<T>( &mut self, src: &A::Buffer, dst: &A::Buffer, regions: T )where T: Iterator<Item = BufferCopy>,

unsafe fn copy_texture_to_texture<T>( &mut self, src: &A::Texture, src_usage: TextureUses, dst: &A::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: &A::Buffer, dst: &A::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: &A::Texture, src_usage: TextureUses, dst: &A::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 set_bind_group( &mut self, layout: &A::PipelineLayout, index: u32, group: &A::BindGroup, dynamic_offsets: &[DynamicOffset] )

Sets the bind group at index to group, assuming the layout of all the preceeding groups to be taken from layout.

unsafe fn set_push_constants( &mut self, layout: &A::PipelineLayout, stages: ShaderStages, offset: u32, data: &[u32] )
