dask_awkward.Scalar#

class dask_awkward.Scalar(dsk, name, meta=None, dtype=None, known_value=None)[source]#

Single partition Dask collection representing a lazy Scalar.

The class constructor is not intended for users. Instances of this class will be results from awkward operations.

Within dask-awkward the new_scalar_object and new_known_scalar factory functions are used for creating new instances.

Parameters:

__init__(dsk, name, meta=None, dtype=None, known_value=None)[source]#

Parameters:

Return type:

None
