Module gfx_hal::command

Command buffers.

A command buffer collects a list of commands to be submitted to the device. Each command buffer has specific capabilities for graphics, compute or transfer operations, and can be either a "primary" command buffer or a "secondary" command buffer. Operations always start from a primary command buffer, but a primary command buffer can contain calls to secondary command buffers that contain snippets of commands that do specific things, similar to function calls.

All the possible commands are implemented in the RawCommandBuffer trait, and then the CommandBuffer and related types make a generic, strongly-typed wrapper around it that only expose the methods that are valid for the capabilities it provides.

Structs

BufferCopy	Specifies a source region and a destination region in a buffer for copying. All values are in units of bytes.
BufferImageCopy	Bundles together all the parameters needed to copy a buffer to an image or vice-versa.
ClearDepthStencil	A combination of depth and stencil clear values.
CommandBufferFlags	Option flags for various command buffer settings.
CommandBufferInheritanceInfo
ImageBlit	Parameters for an image blit operation, where a portion of one image is copied into another, possibly with scaling and filtering.
ImageCopy	Bundles together all the parameters needed to copy data from one Image to another.
ImageResolve	Parameters for an image resolve operation, where a multi-sampled image is copied into a single-sampled image.

Enums

AttachmentClear	Attachment clear description for the current subpass.
Level	An enum that indicates at runtime whether a command buffer is primary or secondary, similar to what command::Primary and command::Secondary do at compile-time.
SubpassContents	Specifies how commands for the following renderpasses will be recorded.

Traits

CommandBuffer

A trait that describes all the operations that must be provided by a Backend's command buffer.

Type Definitions

DescriptorSetOffset

Offset for dynamic descriptors.

Unions

ClearColor	A clear color union, which can be either f32, i32, or u32.
ClearValue	A set of clear values for a single attachment.
