…r the same operation.
…thing, we'll just use associated functions.
…t r0 before calling the assembly handler, which apparently exist.

@zesterer You're the closest i have to a reviewer. This needs work to be complete and to be consistent, but I hope most of the direction of this is clear and looks good. |

I'd love a keys.changes_from(keys_old) here, quite useful when trying to detect key presses, especially given than the BitAnd impl seems to have gone.
Edit: Perhaps keys.presses_since(keys_old) and keys.releases_since(keys_old) actually?

I know I mentioned it before, but I'd like to see all of this track_caller-ed to hell and back. Extra important given that the default GBA targets don't support unwinding so the only panic location you get is the one the compiler gives you at the panic site.

Also, bytemuck integration would be lovely. num_traits too, if at all possible. I've ended up writing my own fixed-point type because sadly these types don't fill these gaps.

Maybe mention alloc + give hints about where to go when looking to set it up? I don't use it myself, but I gather that it's common to place the heap in ewram. Something like linked_list_allocator seems like a good choice.

Since asm_const is stabilized in nightly, and since const_mut_ref is on path to be stablilized "soon", I think there's less and less reason to have a big breaking change update, so I'm gonna close this. |
fixedcrate for fixed point, instead of reimplementing #185TODO:
mmiomodule and just place controls and their data types into each peripheral's module (Video, Timers, etc).t32anda32versions of key BIOS calls so that they can always cleanly inline
