        `Documentation <http://thriftrw.readthedocs.org/en/latest/>`_ is available on
        Read The Docs.

        Features
        --------
        
        * No code generation. The ``.thrift`` files are parsed and compiled in-memory
          at runtime.
        * No assumptions about how bytes are sent or received. The library
          concerns itself with serialization and deserialization only.
        * Supports Python 2 and 3.
        * Forward and cyclic references in types.
        
        Example
        -------
        
        Given the ``.thrift`` file,::
        
            // blog.thrift
        
            typedef string PostUUID
        
            typedef binary RichText
        
            union Body {
                1: string plainText
                2: RichText richText
            }
        
            struct PostDetails {
                1: required string author
                2: required string subject
                3: required Body body
            }
        
            exception UnauthorizedRequestError {
            }
        
            service BlogService {
                PostUUID newPost(1: PostDetails post)
                    throws (1: UnauthorizedRequestError unauthorized);
            }
        
        
        You can use the library to send and receive requests and responses like so,
        
        .. code-block:: python
        
            # client.py
        
            import thriftrw
        
            blog = thriftrw.load('blog.thrift')
            BlogService = blog.BlogService
        
            def new_post():
                post = blog.PostDetails(
                    author='...',
                    subject='...',
                    body=blog.Body(plainText='Hello, world!')
                )
        
                request = BlogService.newPost.request(post)
                payload = blog.dumps(request)
        
                # send_to_server is implemented by the user.
                response_payload = send_to_server(payload)
                response = blog.loads(BlogService.newPost.response, response_payload)
                if response.unauthorized is not None:
                    raise response.unauthorized
                else:
                    return response.success
        
        
        .. code-block:: python
        
            # server.py
        
            import thriftrw
        
            blog = thriftrw.load('blog.thrift')
            BlogService = blog.BlogService
        
            # The user's server handler calls handle_new_post with the payload.
            def handle_new_post(request_payload):
                request = blog.loads(BlogService.newPost.request, request_payload)
                if request.post.author != 'admin':
                    response = BlogService.newPost.response(
                        unauthorized=blog.UnauthorizedRequestError()
                    )
                else:
                    # create_post is implemented by the user.
                    post_uuid = create_post(request.post)
                    response = BlogService.newPost.response(success=post_uuid)
        
                return blog.dumps(response)
        
        Message Envelopes
        ~~~~~~~~~~~~~~~~~
        
        Note that this example sends and receives just the request/response payload. It
        does not wrap the payload in a message envelope as expected by Apache Thrift.
        If you want to send or receive standard Apache Thrift requests to talk to other
        Apache Thrift services, you have to use the ``loads.message`` and
        ``dumps.message`` APIs. For example,
        
        .. code-block:: python
        
            # client.py
        
            def new_post():
                post = blog.PostDetails(...)
                request = BlogService.newPost.request(post)
                payload = blog.dumps.message(request)
                # ^ Instead of using blog.dumps, we use blog.dumps.message to indicate
                # that we want the request wrapped in a message envelope.
        
        
                response_payload = send_to_server(payload)
        
                # Similarly, instead of using blog.loads, we use blog.loads.message to
                # indicate that we want to parse a response stored inside a message.
                response_message = blog.loads.message(BlogService, response_payload)
                response = response_message.body
        
                if response.unauthorized is not None:
                    raise response.unauthorized
                else:
                    return response.success
        
        
        .. code-block:: python
        
            # server.py
        
            def handle_request(request_payload):
                message = blog.loads.message(BlogService, request_payload)
                if message.name == 'newPost':
                    request = message.body
                    # ...
                    response = BlogService.newPost.response(success=post_uuid)
                    return blog.dumps.message(response, seqid=message.seqid)
                    # As before, we use blog.dumps.message instead of blog.dumps.
                    # It is important that the server use the same seqid in the
                    # response as what was used in the request, otherwise the client
                    # will not be able to process out-of-order responses.
                else:
                    raise Exception('Unknown method %s' % message.name)

        Caveats
        -------
        
        * Only the Thrift Binary protocol is supported at this time.
