Trait gstreamer::prelude::OptionMulAssign

pub trait OptionMulAssign<Rhs = Self, InnerRhs = Rhs> {
    fn opt_mul_assign(&mut self, rhs: Rhs);
}

Trait for values and Options multiplication assignment.

Implementing this trait leads to the following auto-implementations:

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

This trait is auto-implemented for OptionOperations types implementing Mul<Rhs>.

Required Methods

fn opt_mul_assign(&mut self, rhs: Rhs)

Performs the multiplication assignment.

self is unchanged if rhs is None.
