Trait rayon::iter::internal::Producer

pub trait Producer: Send + Sized {
    type Item;
    type IntoIter: Iterator<Item = Self::Item> + DoubleEndedIterator + ExactSizeIterator;
    fn into_iter(self) -> Self::IntoIter;
    fn split_at(self, index: usize) -> (Self, Self);

    fn min_len(&self) -> usize { ... }
    fn max_len(&self) -> usize { ... }
    fn fold_with<F>(self, folder: F) -> F
    where
        F: Folder<Self::Item>,
    { ... }
}

A producer which will produce a fixed number of items N. This is not queryable through the API; the consumer is expected to track it.

Associated Types

type Item

type IntoIter: Iterator<Item = Self::Item> + DoubleEndedIterator + ExactSizeIterator

Required methods

fn into_iter(self) -> Self::IntoIter

fn split_at(self, index: usize) -> (Self, Self)

Split into two producers; one produces items 0..index, the other index..N. Index must be less than or equal to N.

Provided methods

fn min_len(&self) -> usize

fn max_len(&self) -> usize

fn fold_with<F>(self, folder: F) -> F where
    F: Folder<Self::Item>, 

Iterate the producer, feeding each element to folder, and stop when the folder is full (or all elements have been consumed).

The provided implementation is sufficient for most iterables.
