Trait differential_dataflow::trace::layers::TupleBuilder

pub trait TupleBuilder: Builder {
    type Item;
    fn new() -> Self;
    fn with_capacity(cap: usize) -> Self;
    fn push_tuple(&mut self, tuple: Self::Item);
}

A type used to assemble collections from ordered sequences of tuples.

Associated Types
