class RenderPass

Defined at line 53 of file ../../src/ui/lib/escher/third_party/granite/vk/render_pass.h

RenderPass encapsulates a Vulkan render pass. Once constructed, it behaves

as a simple container. However, the construction process is fairly involved,

due to the boilerplate required by Vulkan. See the constructor comment for

additional details, as well as the RenderPassInfo documentation.

NOTE: this class is an implementation detail of CommandBuffer; Escher clients

are never directly exposed to it. Instead, they use RenderPassInfo.

TODO(https://fxbug.dev/42151081): RenderPass and Framebuffer are deprecated, to be replaced by

impl::RenderPass and impl::Framebuffer. The latter two aren't visible to

Escher clients; they are an implementation detail of escher::CommandBuffer

(NOTE: NOT escher::impl::CommandBuffer, which is also deprecated).

void RenderPass (ResourceRecycler * recycler, const RenderPassInfo & info)

In order to create a VkRenderPass, Vulkan requires explicit info about e.g.

which attachments are used in which subpasses, which subpasses are depended

upon by other subpasses, which image layouts should be used by for each

image in each subpass, etc. This constructor takes a RenderPassInfo as

input, from which it generates a VkRenderPassCreateInfo containing the

explicit specification required by Vulkan. See RenderPassInfo for more

details.
