Description of changes:
Relevant changes to rustc:
<*const T>::guaranteed_*
methods now return an option for the unknown case rust-lang/rust#101483: Change to intrinsics.Resolved issues:
Fixes #1615
Related RFC:
Optional #ISSUE-NUMBER.
Call-outs:
I created a special case for the niche optimization to keep using
struct
instead ofunion
for cases where the enumeration only has one non-ZST variant. Without this, thekani
test suite takes more than 30min to finish. My guess is that it impacts a lot ofOption<>
and common enums out there.Testing:
How is this change tested? New tests
Is this a refactor change? No
