Trait NdProducer 

pub trait NdProducer {
    type Item;
    type Dim: Dimension;

    // Required method
    fn raw_dim(&self) -> Self::Dim;
}

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 correspondence 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 Associated Types

type Item

The element produced per iteration.

type Dim: Dimension

Dimension type

Required Methods

fn raw_dim(&self) -> Self::Dim

Return the shape of the producer.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
