resolve_bytes()

std::optional< Kakshya::DataVariant > MayaFlux::Buffers::DataReadProcessor::resolve_bytes

(

)

Finish the read as raw bytes.

Waits for a device-local transfer when necessary. Call outside the graphics processing thread. A pixel read yields its raw pixel bytes. Returns nullopt if no result is pending or the pending result is a MeshBuffer copy; use resolve_mesh() for that.
