Enum vulkano::render_pass::StoreOp [−][src]
#[repr(i32)]
pub enum StoreOp {
Store,
DontCare,
}
Expand description
Describes what the implementation should do with an attachment after all the subpasses have completed.
Variants
Store
The attachment will be stored. This is what you usually want.
While this is the most intuitive option, it is also slower than DontCare
because it can
take time to write the data back to memory.
DontCare
What happens is implementation-specific.
This is purely an optimization compared to Store
. The implementation doesn’t need to copy
from the internal cache to the memory, which saves memory bandwidth.
This doesn’t mean that the data won’t be copied, as an implementation is also free to not use a cache and write the output directly in memory. In other words, the content of the image will be undefined.
