Methods

impl<A: ErasablePtr, B: ErasablePtr, C: ErasablePtr, D: ErasablePtr> Enum4<A, B, C, D>

pub fn pack(self, proof: UnionBuilder<Union4<A, B, C, D>>) -> Union4<A, B, C, D>

Pack this loose enum into a pointer union.

pub unsafe fn pack_unchecked(self) -> Union4<A, B, C, D>

Pack this loose enum into a pointer union.

Safety

The used pointer must align to at least u32 (#[repr(align(4))]).
