Simon Sapin	9e4865b6c8	Replace NonZeroU32 and NonZeroUsize with a generic NonZero ... The API is identical to core::nonzero::NonZero	2017-10-16 20:19:19 +02:00
Simon Sapin	4ee1b26b6c	Give up on NonZeroUsize memory layout optimization with unstable features. ... I’m not confident of the implications regarding variance, dropck, struct aliasing, etc. when this is extended to generic `*const T` and `*mut T`. Release builds should use `unstable` to enable other optimizations anyway.	2017-10-16 20:19:18 +02:00
