Patrick Walton 5b746d2b19 Pack the `StandardMaterialKey` into a single scalar instead of a structure. (#12783 ) This commit changes the `StandardMaterialKey` to be based on a set of bitflags instead of a structure. We hash it every frame for every mesh, and `#[derive(Hash)]` doesn't generate particularly efficient code for large structures full of small types. Packing it into a single `u64` therefore results in a roughly 10% speedup in `queue_material_meshes` on `many_cubes --no-frustum-culling`. ![Screenshot 2024-03-29 075124](https://github.com/bevyengine/bevy/assets/157897/78afcab6-b616-489b-8243-da9a117f606c)	2024-03-29 18:34:27 +00:00

Pack the StandardMaterialKey into a single scalar instead of a structure. (#12783 )

This commit changes the `StandardMaterialKey` to be based on a set of
bitflags instead of a structure. We hash it every frame for every mesh,
and `#[derive(Hash)]` doesn't generate particularly efficient code for
large structures full of small types. Packing it into a single `u64`
therefore results in a roughly 10% speedup in `queue_material_meshes` on
`many_cubes --no-frustum-culling`.
