switch to nightly and enable portable_simd feature i really did not want to use nightly, but i think it is worth it for portable_simd which is still nightly-only (and i'm guessing will be for a long while still). i was not particularly enthusiastic about any of the alternative libraries that exist for stable rust simd, as it always seemed like something small was missing from what i knew i would want longer term. 2023-04-19 17:31:48 -04:00			`[toolchain]`

specify nightly toolchain by date i did not expect this to be problematic so soon, based on what i'd read in various places about the stability of nightly (especially so for the most common platforms like x86_64, etc) as i write this commit message, all nightly versions past this date fail to build ggdt, failing with an "illegal instruction" error. sigh. this makes me question whether trying to use simd right now is actually worth it ... 2023-04-20 23:00:51 -04:00			`channel = "nightly-2023-04-17"`
