pub struct Counter<T, C, P: Push<Message<T, C>>> { /* private fields */ }

A wrapper which updates shared produced based on the number of records pushed.

Implementations

impl<T, C, P: Push<Message<T, C>>> Counter<T, C, P>

where T: Ord + Clone + 'static,

pub fn new(pushee: P) -> Counter<T, C, P>

Allocates a new Counter from a pushee and shared counts.

pub fn produced(&self) -> &Rc<RefCell<ChangeBatch<T>>>

A references to shared changes in counts, for cloning or draining.
