Dependency info for barriers in a pipeline barrier or event command.

A pipeline barrier creates a dependency between commands submitted before the barrier (the source scope) and commands submitted after it (the destination scope). An event command acts like a split pipeline barrier: the source scope and destination scope are defined relative to different commands. Each DependencyInfo consists of multiple individual barriers that concern a either single resource or operate globally.

Each barrier has a set of source/destination pipeline stages and source/destination memory access types. The pipeline stages create an execution dependency: the src_stages of commands submitted before the barrier must be completely finished before before any of the dst_stages of commands after the barrier are allowed to start. The memory access types create a memory dependency: in addition to the execution dependency, any src_access performed before the barrier must be made available and visible before any dst_access are made after the barrier.

Fields

dependency_flags: DependencyFlags

Flags to modify how the execution and memory dependencies are formed.

The default value is empty.

memory_barriers: SmallVec<[MemoryBarrier; 2]>

Memory barriers for global operations and accesses, not limited to a single resource.

The default value is empty.

buffer_memory_barriers: SmallVec<[BufferMemoryBarrier; 8]>

Memory barriers for individual buffers.

The default value is empty.

image_memory_barriers: SmallVec<[ImageMemoryBarrier; 8]>

Memory barriers for individual images.

The default value is empty.
