fn opt_checked_div(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>;
}Expand description
Trait for values and Options checked division.
Implementing this trait leads to the following auto-implementations:
OptionCheckedDiv<Option<InnerRhs>>forT.OptionCheckedDiv<Rhs>forOption<T>.OptionCheckedDiv<Option<InnerRhs>>forOption<T>.- … and some variants with references.
Note that since the std library doesn’t define any
CheckedDiv trait,
users must provide the base implementation for the inner type.
