Struct bedrock::SubpassDescription

pub struct SubpassDescription { /* fields omitted */ }

Builder structure to construct the VkSubpassDescription

The layout parameter of each attachment

The layout parameter describes what layout the attachment will be in during the subpass.

How input attachments work

• Each element of the array corresponds to an input attachment unit number in the shader.
  • i. e. if the shader declares an input variable layout(input_attachment_index=X, set=Y, binding=Z) then it uses the attachment provided in input_attachments[X].
• Input attachments must also be bound to the pipeline with a descriptor set, with the input attachment descriptor written in the location (set=Y, binding=Z).
• Fragment shaders can use subpass input variables to access the contents of an input attachment at the fragment's (x, y, layer) framebuffer coordinates.
