Object Safety§

This trait is not object safe.

Implementations on Foreign Types§

source §

impl<T: Copy> ToTotalOrd for Option<T>

This is safe without needing to map the option value to TotalOrdWrap, since for example: TotalOrdWrap<Option<T>> implements Eq + Hash, iff: Option<T> implements TotalEq + TotalHash, iff: T implements TotalEq + TotalHash
