SocketAddrV6 in std::net - Rust (original) (raw)
Struct SocketAddrV6
1.0.0 · Source
pub struct SocketAddrV6 { /* private fields */ }Expand description
An IPv6 socket address.
IPv6 socket addresses consist of an IPv6 address, a 16-bit port number, as well as fields containing the traffic class, the flow label, and a scope identifier (see IETF RFC 2553, Section 3.3 for more details).
See SocketAddr for a type encompassing both IPv4 and IPv6 socket addresses.
The size of a SocketAddrV6 struct may vary depending on the target operating system. Do not assume that this type has the same memory layout as the underlying system representation.
§Textual representation
SocketAddrV6 provides a FromStr implementation, based on the bracketed format recommended by IETF RFC 5952, with scope identifiers based on those specified in IETF RFC 4007.
It accepts addresses consisting of the following elements, in order:
- A left square bracket (
[) - The textual representation of an IPv6 address
- Optionally, a percent sign (
%) followed by the scope identifier encoded as a decimal integer - A right square bracket (
]) - A colon (
:) - The port, encoded as a decimal integer.
For example, the string [2001:db8::413]:443 represents a SocketAddrV6with the address 2001:db8::413 and port 443. The string[2001:db8::413%612]:443 represents the same address and port, with a scope identifier of 612.
Other formats are not accepted.
§Examples
use std:🥅:{Ipv6Addr, SocketAddrV6};
let socket = SocketAddrV6::new(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 1), 8080, 0, 0);
assert_eq!("[2001:db8::1]:8080".parse(), Ok(socket));
assert_eq!(socket.ip(), &Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 1));
assert_eq!(socket.port(), 8080);
let mut with_scope = socket.clone();
with_scope.set_scope_id(3);
assert_eq!("[2001:db8::1%3]:8080".parse(), Ok(with_scope));🔬This is a nightly-only experimental API. (addr_parse_ascii #101035)
