Trait option_operations::mul::OptionSaturatingMul

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

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

Trait for values and Options saturating multiplication.

Implementing this trait leads to the following auto-implementations:

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

Note that since the std library doesn’t define any SaturatingMul 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_saturating_mul(self, rhs: Rhs) -> Option<Self::Output>

Computes the multiplication saturating at the numeric bounds instead of overflowing.

Returns None if at least one argument is None.
