inline

Returns a proxy object that provides access to the array's data without bounds or dimensionality checking. Will throw if the array is missing the writeable flag. Use with care: the array must not be destroyed or reshaped for the duration of the returned object, and the caller must take care not to access invalid dimensions or dimension indices.

inline

Returns a proxy object that provides const access to the array's data without bounds or dimensionality checking. Unlike unchecked(), this does not require that the underlying array have the writable flag. Use with care: the array must not be destroyed or reshaped for the duration of the returned object, and the caller must take care not to access invalid dimensions or dimension indices.
