role_type is in boost/beast/core/role.hpp (API Change):

This enumeration is now part of the library core and
not specific to websocket.

-/** The role of the websocket stream endpoint.
-
-    Whether the endpoint is a client or server affects the
-    behavior of the <em>Close the WebSocket Connection</em>
-    operation described in rfc6455 section 7.1.1.
-    The shutdown behavior depends on the type of the next
-    layer template parameter used to construct the @ref stream.
-    Other next layer types including user-defined types
-    may implement different role-based behavior when
-    performing the close operation.
-    
-    The default implementation for @ref stream when the next
-    layer type is a `net::ip::tcp::socket` behaves
-    as follows:
-
-    @li In the client role, a TCP/IP shutdown is sent after
-    reading all remaining data on the connection.
-
-    @li In the server role, a TCP/IP shutdown is sent before
-    reading all remaining data on the connection.
-
-    When the next layer type is a `net::ssl::stream`,
-    the connection is closed by performing the SSL closing
-    handshake corresponding to the role type, client or server.
-
-    @see https://tools.ietf.org/html/rfc6455#section-7.1.1
