Trait core::ops::MulAssign
[−]
[src]
pub trait MulAssign<Rhs = Self> {
fn mul_assign(&mut self, Rhs);
}The MulAssign trait is used to specify the functionality of *=.
Examples
A trivial implementation of MulAssign. When Foo *= Foo happens, it ends up
calling mul_assign, and therefore, main prints Multiplying!.
