Module 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 are always initiated by 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 exposed by the CommandBuffer trait.

Structs

• BufferCopy
  Specifies a source region and a destination region in a buffer for copying. All values are in units of bytes.

• 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.
• RenderAttachmentInfo
  A render attachment provided to begin_render_pass.

Enums

• AttachmentClear
  Attachment clear description for the current subpass.
• Level
  An enum that indicates whether a command buffer is primary or secondary.
• SubpassContents
  Specifies how commands for the following render passes will be recorded.

Traits

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

Type Aliases

• 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.
