Enum sierra::AttachmentLoadOp

pub enum AttachmentLoadOp {
    Load,
    Clear,
    DontCare,
}

Specifies how render pass treats attachment content at the beginning.

Variants

Load

Render pass will load this attachment content before first subpass that access this attachment starts.

Clear

Render pass will clear this attachment content before first subpass that access this attachment starts. Value to which attachment should be cleared must be provided in Encoder::begin_render_pass call.

DontCare

Render pass will not attempt to load attachment content or clear it - basically no-op. Attachment content visible to read operations inside render pass is undefined before it is written.

This is fastest variant suitable when old content can be discarded and whole attachment is going to be written by operations in render pass, or only written parts are later read.
