Struct esp_idf_svc::ipv4::SocketAddrV6

1.0.0 ·

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.

§Examples

use std::net::{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);

Implementations§

§

impl SocketAddrV6

pub fn parse_ascii(b: &[u8]) -> Result<SocketAddrV6, AddrParseError>

🔬This is a nightly-only experimental API. (addr_parse_ascii)

Parse an IPv6 socket address from a slice of bytes.

#![feature(addr_parse_ascii)]

use std::net::{Ipv6Addr, SocketAddrV6};

let socket = SocketAddrV6::new(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 1), 8080, 0, 0);

assert_eq!(SocketAddrV6::parse_ascii(b"[2001:db8::1]:8080"), Ok(socket));

impl SocketAddrV6

1.0.0 (const: 1.69.0)

pub const fn new( ip: Ipv6Addr, port: u16, flowinfo: u32, scope_id: u32, ) -> SocketAddrV6

Creates a new socket address from an IPv6 address, a 16-bit port number, and the flowinfo and scope_id fields.

For more information on the meaning and layout of the flowinfo and scope_id parameters, see IETF RFC 2553, Section 3.3.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 0);

1.0.0 (const: 1.69.0)

pub const fn ip(&self) -> &Ipv6Addr

Returns the IP address associated with this socket address.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 0);
assert_eq!(socket.ip(), &Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1));

1.9.0

pub fn set_ip(&mut self, new_ip: Ipv6Addr)

Changes the IP address associated with this socket address.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let mut socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 0);
socket.set_ip(Ipv6Addr::new(76, 45, 0, 0, 0, 0, 0, 0));
assert_eq!(socket.ip(), &Ipv6Addr::new(76, 45, 0, 0, 0, 0, 0, 0));

1.0.0 (const: 1.69.0)

pub const fn port(&self) -> u16

Returns the port number associated with this socket address.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 0);
assert_eq!(socket.port(), 8080);

1.9.0

pub fn set_port(&mut self, new_port: u16)

Changes the port number associated with this socket address.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let mut socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 0);
socket.set_port(4242);
assert_eq!(socket.port(), 4242);

1.0.0 (const: 1.69.0)

pub const fn flowinfo(&self) -> u32

Returns the flow information associated with this address.

This information corresponds to the sin6_flowinfo field in C’s netinet/in.h, as specified in IETF RFC 2553, Section 3.3. It combines information about the flow label and the traffic class as specified in IETF RFC 2460, respectively Section 6 and Section 7.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 10, 0);
assert_eq!(socket.flowinfo(), 10);

1.9.0

pub fn set_flowinfo(&mut self, new_flowinfo: u32)

Changes the flow information associated with this socket address.

See SocketAddrV6::flowinfo’s documentation for more details.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let mut socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 10, 0);
socket.set_flowinfo(56);
assert_eq!(socket.flowinfo(), 56);

1.0.0 (const: 1.69.0)

pub const fn scope_id(&self) -> u32

Returns the scope ID associated with this address.

This information corresponds to the sin6_scope_id field in C’s netinet/in.h, as specified in IETF RFC 2553, Section 3.3.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 78);
assert_eq!(socket.scope_id(), 78);

1.9.0

pub fn set_scope_id(&mut self, new_scope_id: u32)

Changes the scope ID associated with this socket address.

See SocketAddrV6::scope_id’s documentation for more details.

§Examples

use std::net::{SocketAddrV6, Ipv6Addr};

let mut socket = SocketAddrV6::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8080, 0, 78);
socket.set_scope_id(42);
