Move most uses of the std crate to core and alloc #196

Closed linkmauve closed 2 years ago

linkmauve commented 2 years ago

std::io and std::error::Error are the two remaining uses of std preventing this crate from building in a #![no_std] context.

I’ve tried reimplementing just these parts of std in this crate, but it was obviously not a good way forward, and I don’t know what could be a way forward here. In the meantime, these changes don’t cause any issue, and will be useful for the next person trying to implement no_std!

f32::ceil() and f32::fract() are two other functions we use which are available only in std, I’m not too sure why.

@fintelia Your judgment, should we do the same as in the other crates—move to 0.2 and bump to 1.48? Note that we'll need to do a breaking release in any case after #193 is merged.
