43#
44# Captures a socket address or address range in the Internet namespace.

46# @numeric: true if the host/port are guaranteed to be numeric,

79#         (only matters for abstract sockets, default true). (Since 5.1)

110#
111# Captures the address of a socket, which could also be a named file descriptor
112#
113# Note: This type is deprecated in favor of SocketAddress.  The
114#       difference between SocketAddressLegacy and SocketAddress is that the
115#       latter is a flat union rather than a simple union. Flat is nicer
116#       because it avoids nesting on the wire, i.e. that form has fewer {}.
