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
Specifies a source region and a destination
region in a buffer for copying. All values
are in units of bytes.
Bundles together all the parameters needed to copy a buffer
to an image or vice-versa.
Depth-stencil target clear values.
A variant of
ClearDepthStencil that has a #[repr(C)] layout
and so is used when a known layout is needed.A strongly-typed command buffer that will only implement methods that are valid for the operations
it supports.
Option flags for various command buffer settings.
Parameters for an image blit operation, where a portion of one image
is copied into another, possibly with scaling and filtering.
Bundles together all the parameters needed to copy data from one
Image
to another.Parameters for an image resolve operation,
where a multi-sampled image is copied into a single-sampled
image.
An object that records commands into a command buffer inline, that is,
without secondary command buffers.
An object that records commands into a command buffer where each command must
be a call to execute a secondary command buffer.
This struct contains all methods for all commands submittable during a subpass.
It is used to implement the identical portions of RenderPassInlineEncoder and SubpassCommandBuffer.
A secondary command buffer recorded entirely within a subpass.
Enums
Attachment clear description for the current subpass.
A universal clear color supporting integer formats
as well as the standard floating-point.
General clear values for attachments (color or depth-stencil).
Indicates a Submit that can be submitted multiple times.
Indicates a Submit that can only be submitted once.
Indicates a primary command buffer.
Vulkan describes a primary command buffer as one which can be directly submitted
to a queue, and can execute
Secondary command buffers.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.Indicates a secondary command buffer.
Specifies how commands for the following renderpasses will be recorded.
Traits
A trait indicating the level of a command buffer.
A trait that describes all the operations that must be
provided by a
Backend’s command buffer.Trait indicating how many times a Submit object can be submitted to a command buffer.
A property of a command buffer to be submitted to a queue with specific capability.
Type Definitions
Offset for dynamic descriptors.
A convenience alias for not typing out the full signature of a secondary command buffer.
Unions
Unsafe variant of
ClearColor.Unsafe variant of
ClearValue.
