# Struct std::net::Ipv6Addr 1.0.0[−][src]

    pub struct Ipv6Addr { /* fields omitted */ }

An IPv6 address.

IPv6 addresses are defined as 128-bit integers in IETF RFC 4291. They are usually represented as eight 16-bit segments.

See `IpAddr` for a type encompassing both IPv4 and IPv6 addresses.

The size of an `Ipv6Addr` struct may vary depending on the target operating system.

# Textual representation

`Ipv6Addr` provides a `FromStr` implementation. There are many ways to represent an IPv6 address in text, but in general, each segments is written in hexadecimal notation, and segments are separated by `:`. For more information, see IETF RFC 5952.

# Examples

    use std::net::Ipv6Addr;

    let localhost = Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1);
    assert_eq!("::1".parse(), Ok(localhost));
    assert_eq!(localhost.is_loopback(), true);Run

## Methods

###

`impl Ipv6Addr`

[src]

Creates a new IPv6 address from eight 16-bit segments.

The result will represent the IP address a:b:c:d:e:f:g:h.

# Examples

    use std::net::Ipv6Addr;

    let addr = Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff);Run

####

`pub fn localhost() -> Ipv6Addr`

[src]

🔬 This is a nightly-only experimental API. (`ip_constructors` #44582)

requires greater scrutiny before stabilization

Creates a new IPv6 address representing localhost: `::1`.

# Examples

    #![feature(ip_constructors)]
    use std::net::Ipv6Addr;

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
