Trait option_operations::rem::OptionCheckedRem

pub trait OptionCheckedRem<Rhs = Self, InnerRhs = Rhs> {
    type Output;

    // Required method
    fn opt_checked_rem(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>;
}

Trait for values and Options checked remainder.

Implementing this trait 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.

Required Associated Types

type Output

The resulting inner type after applying the remainder.

Required Methods

fn opt_checked_rem(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>

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::Overflow) if an overflow occured.
• Returns Err(Error::DivisionByZero) if rhs is zero.
