alexcrichton opened PR #4353 from const-size to main:

The more I read over this again the more I think that these should be
constants to explicitly indicate that we're supposed to be able to
optimize for them. Currently I'm predicting that adding memory64 support
will probably double the surface area of each trait (e.g. lower32 and
lower64) rather than have a parameter passed around. This is in the
hopes that having specialized 32 and 64-bit paths will enable better
optimizations within each path instead of having to check all bounds
everywhere.

Additionally one day I'd like to have fn load(bytes: &[u8; Self::SIZE32]) but that doesn't work today in Rust.

Would it be possible to make next_field const so we could keep using it here?

I initially attempted that yeah but in const Rust we apparently can't take &mut references which prevented me from calling that. I figured that the amount of duplication here isn't too too big so I'm hoping it won't be too bad.
