Crop returns a [Map] of a sub-region of the target shape.

New returns a new element implementing the dimensions interface D.

Sampler returns a new Mapper that can flip, drop, or reorder dimensions of shapes arbitrarily.

Mapper can be used to create a [Map] for any shape.

D is the interface implemented by an element that represents the dimensionality (e.g.

Map describes a new set of dimensions formed by applying a mapping operation to an original set of dimensions.

D1 is a 1-dimensional implementation of the [D] interface.

D2 is a 2-dimensional implementation of the [D] interface.

D3 is a 3-dimensional implementation of the [D] interface.

D4 is a 4-dimensional implementation of the [D] interface.
