Parameters
----------
project_id : UUID or None, default=None
The ID(s) of the project to filter by.
project_name : str or None, default=None
The name(s) of the project to filter by.
run_type : str or None, default=None
The type of the runs to filter by.

The query string to filter by.
filter : str or None, default=None
The filter string to filter by.

Filter to apply to the ROOT run in the trace tree. This is meant to
be used in conjunction with the regular `filter` parameter to let you
filter runs by attributes of the root run within a trace.
tree_filter : str or None, default=None
Filter to apply to OTHER runs in the trace tree, including
sibling and child runs. This is meant to be used in conjunction with
the regular `filter` parameter to let you filter runs by attributes
of any run within a trace.
is_root : bool or None, default=None
Whether to filter by root runs.
parent_run_id : UUID or None, default=None
The ID of the parent run to filter by.
start_time : datetime or None, default=None
The start time to filter by.
error : bool or None, default=None
Whether to filter by error status.
run_ids : List[str or UUID] or None, default=None
The IDs of the runs to filter by.
limit : int or None, default=None
The maximum number of runs to return.
**kwargs : Any
Additional keyword arguments.

.. code-block:: python

.. code-block:: python
complex_runs = client.list_runs(
