``transport`` was not explicitly provided, the endpoint is
determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment
variable, which have one of the following values:
"always" (always use the default mTLS endpoint), "never" (always
use the default regular endpoint) and "auto" (auto-switch to the
default mTLS endpoint if client certificate is present; this is
the default value).
2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
is "true", then the ``client_cert_source`` property can be used
to provide a client certificate for mTLS transport. If
not provided, the default SSL client certificate will be used if
present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
set, no client certificate will be used.

currently not supported for mTLS.

**NOTE:** This method requires that you specify a response field

using URL parameter ``$fields`` or ``fields``, or by using an
HTTP/gRPC header ``X-Goog-FieldMask`` (see the `available URL
parameters and
headers <https://cloud.google.com/apis/docs/system-parameters>`__).
The value is a comma separated list of field paths. See detailed
documentation about `how to construct the field
paths <https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/field_mask.proto>`__.
For example, in this method:
- Field mask of all available fields (for manual inspection):
``X-Goog-FieldMask: *``
- Field mask of Route-level duration, distance, and polyline
(an example production setup):
``X-Goog-FieldMask: routes.duration,routes.distanceMeters,routes.polyline.encodedPolyline``
Google discourage the use of the wildcard (``*``) response field
mask, or specifying the field mask at the top level
(``routes``), because:
- Selecting only the fields that you need helps our server save
computation cycles, allowing us to return the result to you
with a lower latency.
- Selecting only the fields that you need in your production
job ensures stable latency performance. We might add more
response fields in the future, and those new fields might
require extra computation time. If you select all fields, or
if you select all fields at the top level, then you might
experience performance degradation because any new field we
add will be automatically included in the response.
- Selecting only the fields that you need results in a smaller
response size, and thus higher network throughput.

The value is a comma separated list of field paths. See this
detailed documentation about `how to construct the field
paths <https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/field_mask.proto>`__.
For example, in this method:
- Field mask of all available fields (for manual inspection):
``X-Goog-FieldMask: *``
- Field mask of route durations, distances, element status,
condition, and element indices (an example production setup):
``X-Goog-FieldMask: originIndex,destinationIndex,status,condition,distanceMeters,duration``
It is critical that you include ``status`` in your field mask as
otherwise all messages will appear to be OK. Google discourages
the use of the wildcard (``*``) response field mask, because:
- Selecting only the fields that you need helps our server save
computation cycles, allowing us to return the result to you
with a lower latency.
- Selecting only the fields that you need in your production
job ensures stable latency performance. We might add more
response fields in the future, and those new fields might
require extra computation time. If you select all fields, or
if you select all fields at the top level, then you might
experience performance degradation because any new field we
add will be automatically included in the response.
- Selecting only the fields that you need results in a smaller
response size, and thus higher network throughput.

Args:
request (Union[google.maps.routing_v2.types.ComputeRouteMatrixRequest, dict]):
The request object. ComputeRouteMatrix request message
retry (google.api_core.retry.Retry): Designation of what errors, if any,
should be retried.
timeout (float): The timeout for this request.
metadata (Sequence[Tuple[str, Union[str, bytes]]]): Key/value pairs which should be
sent along with the request as metadata. Normally, each value must be of type `str`,
but for metadata keys ending with the suffix `-bin`, the corresponding values must
be of type `bytes`.
Returns:
Iterable[google.maps.routing_v2.types.RouteMatrixElement]:
Contains route information computed
for an origin/destination pair in the
ComputeRouteMatrix API. This proto can
be streamed to the client.
