std::net::netip

Status: experimental

Typed IP-address parsing, classification, and addr:port helpers (Go's net/netip shape).

API details and source

The implementation source contains the complete declarations and implementation notes. The table below lists canonical Gossamer call signatures; every item name links directly to its implementation file.

Item	Canonical signature or declaration	Description
host_of	fn host_of(addr_port: String) -> String	Host portion of an addr:port string, or empty on parse failure.
is_loopback	fn is_loopback(addr: String) -> bool	Return true iff the string parses as a loopback IP (127.0.0.1 / ::1).
is_multicast	fn is_multicast(addr: String) -> bool	Return true iff the string parses as a multicast IP.
is_private	fn is_private(addr: String) -> bool	Return true iff the IP is RFC1918 (v4) or ULA fc00::/7 (v6).
is_unspecified	fn is_unspecified(addr: String) -> bool	Return true iff the string parses as the unspecified IP (0.0.0.0 / ::).
is_v4	fn is_v4(addr: String) -> bool	Return true iff the string parses as a v4 IP.
is_v6	fn is_v6(addr: String) -> bool	Return true iff the string parses as a v6 IP.
is_valid	fn is_valid(addr: String) -> bool	Return true iff the string parses as a v4 or v6 IP.
join_addr_port	fn join_addr_port(addr: String, port: i64) -> String	Compose an addr:port string from host and port, or empty on failure.
normalize	fn normalize(addr: String) -> Result<String, errors::Error>	Canonical lowercase form of the IP, or empty string on parse failure.
port_of	fn port_of(addr_port: String) -> i64	Port portion of an addr:port string, or -1 on parse failure.
