Module vulkano::command_buffer::sys

Lowest-level interface for command buffers creation.

This module provides the structs necessary to create command buffers. The main purpose of this module is to provide a nice API, and almost no safety checks are performed except through debug_assert!.

Safety

Each individual function is documented and indicates what exactly must be done in order to be safe.

Things to generally look for when you use an UnsafeCommandBuffer are:

• The objects must be kept alive for at least as long as the command buffer.
• The objects must be properly synchronized and transitionned with pipeline barriers.
• The capabilities of the queue must be checked (for example running a draw operation on a transfer-only queue won't work).
• Some commands can only be called from inside or outside of a render pass.

Structs

BufferCopyRegion	A copy between two buffers.
ImageSubresourcesRange	Range of an image subresource.
PipelineBarrierBuilder	Prototype for a pipeline barrier that's going to be added to a command buffer builder.
UnsafeCommandBuffer
UnsafeCommandBufferBuilder

Enums

Flags	Flags to pass when creating a command buffer.
Kind	Determines the kind of command buffer that we want to create.
