GetCachedFrameData()

const FramebufferAndRenderPass & impeller::TextureVK::GetCachedFrameData

(

SampleCount

const

Retrieve the last framebuffer and render pass object used with this texture.

An empty FramebufferAndRenderPass is returned if there is no cached data for a particular sample count.
