#
# @tcp: host address and port number
#
# This is similar to SocketAddress, only distinction:
#
# 1. GlusterServer is a flat union, SocketAddress is a simple union.
# A flat union is nicer than simple because it avoids nesting
# (i.e. more {}) on the wire.
#
# 2. GlusterServer lacks case 'fd', since gluster doesn't let you
# pass in a file descriptor.
#
# GlusterServer is actually not Gluster-specific, its a
# compatibility evolved into an alternate for SocketAddress.
#
# Since: 2.7
