Trait differential_dataflow::difference::Abelian

pub trait Abelian: Monoid {
    // Required method
    fn negate(&mut self);
}

A Monoid with negation.

This trait extends the requirements of Semigroup to include a negation operator. Several differential dataflow operators require negation in order to retract prior outputs, but not quite as many as you might imagine.

Required Methods

fn negate(&mut self)

The method of std::ops::Neg, for types that do not implement Neg.

Object Safety

This trait is not object safe.
