Instance Property

host

The host portion of the endpoint, interpreted exactly as written.

let host: String

Discussion

Accepted forms mirror the POSIX getaddrinfo(3) + SOCKS5 address types: a dotted IPv4 literal ("127.0.0.1"), a DNS name ("localhost", "torproxy.internal"), or a raw IPv6 literal ("::1"). IPv6 literals are not auto-bracketed by description, so callers producing URLs or proxy tuples from a HostPort must bracket the host themselves (e.g. "[::1]:9050") per RFC 3986 §3.2.2.

Stability: immutable (let) — changes require constructing a new HostPort.
Typical values: "127.0.0.1" for SOCKS/control endpoints, a .onion hostname when populating OnionPortTarget, or a local "localhost" alias when a DNS lookup is cheap enough.
