tV tR # )�CachingStreamWrappera Wrapper around non-seekable streams.
Note that the implementation is tied to the decoder,
not checking for dangerous arguments for the sake
of performance.
The read bytes are kept in an internal cache until
setting _markedPosition which may reset the cache.

Keyword parameters
------------------
size: :py:class:`int`
How many bytes to read (-1 = all available)
context: :py:class:`dict`
Opaque caller context will be attached to exception objects created
by this function.
Yields
------
: :py:class:`bytes` or :py:class:`str` or :py:class:`SubstrateUnderrunError`
Read data or :py:class:`~pyasn1.error.SubstrateUnderrunError`
object if no `size` bytes is readily available in the stream. The
data type depends on Python major version
Raises
------
: :py:class:`~pyasn1.error.EndOfStreamError`
Input stream is exhausted
