Expand description

Trait for values and Options remainder.

Implementing this trait leads to the following auto-implementations:

  • OptionRem<Option<InnerRhs>> for T.
  • OptionRem<Rhs> for Option<T>.
  • OptionRem<Option<InnerRhs>> for Option<T>.
  • … and some variants with references.

This trait is auto-implemented for OptionOperations types implementing Rem<Rhs>.

Required Associated Types§

type Output

The resulting inner type after applying the remainder.

Required Methods§

fn opt_rem(self, rhs: Rhs) -> Option<Self::Output>

Computes the remainder.

Returns None if at least one argument is None.

§Panics

Most implementations will panic if rhs is zero.
