To get a copy of the current context use the
:func:`~contextvars.copy_context` function.
+ Every thread will have a different top-level :class:`~contextvars.Context`
+ object. This means that a :class:`ContextVar` object behaves in a similar
+ fashion to :func:`threading.local()` when values are assigned in different
+ threads.

Context implements the :class:`collections.abc.Mapping` interface.
