Trait gstreamer::prelude::OptionOverflowingMul

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

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

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.
