Struct Wrapper

pub struct Wrapper<I>
where I: Clone + Debug + Eq + Hash + PartialEq + Send + Sync + 'static,
{ /* private fields */ }
Expand description

Wrapper for an item

This is used to pass items through parallel iterators. When the wrapper is dropped, we decrement the processing counter and notify the dispatcher thread through the item_done_tx channel.

Implementations§

Source§

impl<I> Wrapper<I>
where I: Clone + Debug + Eq + Hash + PartialEq + Send + Sync + 'static,

Source

pub fn new(inner: I, counter: Arc<AtomicUsize>, item_done_tx: Sender<I>) -> Self

Create a new Wrapper item

This needs a reference to the processing counter to keep count of the number of items currently processed (used to check for circular dependencies) and the item done channel to notify the dispatcher thread.

Upon creating of a Wrapper, we also increment the processing counter.
