Trait combine::primitives::Positioner

pub trait Positioner: PartialEq {
    type Position: Clone + Ord;
    fn start() -> Self::Position;
    fn update(&self, position: &mut Self::Position);
}

Trait for updating the position for types which can be yielded from a Stream.

Associated Types

type Position: Clone + Ord

The type which keeps track of the position.

Required Methods

fn start() -> Self::Position

Creates a start position

fn update(&self, position: &mut Self::Position)

Updates the position given that self has been taken from the stream
