Trait OptionOverflowingMul 

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

    // Required method
    fn opt_overflowing_mul(self, rhs: Rhs) -> Option<(Self::Output, bool)>;
}
Expand description

Trait for values and Options overflowing multiplication.

Implementing this trait leads to the following auto-implementations:

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

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

Required Associated Types§

type Output

The resulting inner type after applying the multiplication.

Required Methods§

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

Returns a tuple of the multiplication along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then self is returned.

Returns None if at least one argument is None.
