Trait option_operations::rem::OptionCheckedRem[−][src]

pub trait OptionCheckedRem<Rhs = Self, InnerRhs = Rhs> {
    type Output;
    fn opt_checked_rem(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>;
}
Expand description

Trait for values and Options checked remainder.

Implementing this type leads to the following auto-implementations:

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

Note that since the std library doesn’t define any CheckedRem trait, users must provide the base implementation for the inner type.

Associated Types

The resulting inner type after applying the operation.

Required methods

Computes the checked remainder.

  • Returns Ok(Some(result)) if result could be computed.
  • Returns Ok(None) if at least one argument is None.
  • Returns Err(Error::DivisionByZero) if rhs is zero.
  • Returns Err(Error::Overflow) if an overflow occured.
