Trait rayon::iter::plumbing::ProducerCallback

pub trait ProducerCallback<T> {
    type Output;

    // Required method
    fn callback<P>(self, producer: P) -> Self::Output
       where P: Producer<Item = T>;
}

The ProducerCallback trait is a kind of generic closure, analogous to FnOnce. See the corresponding section in the plumbing README for more details.

Required Associated Types

type Output

The type of value returned by this callback. Analogous to Output from the FnOnce trait.

Required Methods

fn callback<P>(self, producer: P) -> Self::Output

where P: Producer<Item = T>,

Invokes the callback with the given producer as argument. The key point of this trait is that this method is generic over P, and hence implementors must be defined for any producer.

Object Safety

This trait is not object safe.

Implementors

impl<T, S, C> ProducerCallback<T> for BlocksCallback<S, C>

where C: UnindexedConsumer<T>, S: Iterator<Item = usize>,

type Output = <C as Consumer<T>>::Result
