Map-style DataPipes
===========================

.. currentmodule:: torchdata.datapipes.map

A Map-style DataPipe is one that implements the ``__getitem__()`` and ``__len__()`` protocols, and represents a map
from (possibly non-integral) indices/keys to data samples.

For example, when accessed with ``mapdatapipe[idx]``, could read the ``idx``-th image and its
corresponding label from a folder on the disk.
