Faster bound resource expectation #115

Closed kvark closed 5 years ago

kvark commented 6 years ago

As our buffers and images are all stored as enum { Bound, Unbound }, it requires a match/branch on each and every access. This may show up in the profiles, even if a lower priority than using iterators everywhere. We need a build mode that avoids those branches and just transmutes the thing where it's expected.

The Bound <-> Unbound difference is nice for typesafety but will probably fall apart for sparse resources at some point. So we could merge those again or keep it in HAL and adjust it for portability in case we go with the BAL approach.

This is not a problem as of https://github.com/gfx-rs/gfx/pull/2518
