Expand description

A producer of an n-dimensional set of elements; for example an array view, mutable array view or an iterator that yields chunks.

Producers are used as a arguments to Zip and azip!().

Comparison to IntoIterator

Most NdProducers are iterable (implement IntoIterator) but not directly iterators. This separation is needed because the producer represents a multidimensional set of items, it can be split along a particular axis for parallelization, and it has no fixed correspondance to a sequence.

The natural exception is one dimensional producers, like AxisIter, which implement Iterator directly (AxisIter traverses a one dimensional sequence, along an axis, while producing multidimensional items).

Required methods

Return the shape of the producer.

This trait is private to implement; this method exists to make it impossible to implement outside the crate.
