 The driver raises a ``WriteError`` error for any errors that it
-encounters when performing a write operation that are not related to

-error, the ``WriteError`` type contains fields that describe the type of
-write error and reason for the error.

-For example, the driver raises a ``WriteError`` error if you attempt to
-insert a document into a collection that violates the collection's
-schema validation rules. Suppose the collection has a rule where the
-value of the ``quantity`` field must be an ``int`` type. If you
