Union SockaddrStorage

#[repr(C)]
pub union SockaddrStorage {
    /* private fields */
}

A container for any sockaddr type

Just like C’s sockaddr_storage, this type is large enough to hold any type of sockaddr. It can be used as an argument with functions like bind and getsockname. Though it is a union, it can be safely accessed through the as_* methods.

Example

let localhost = SockaddrIn::from_str("127.0.0.1:8081").unwrap();
let fd = socket(AddressFamily::Inet, SockType::Stream, SockFlag::empty(),
    None).unwrap();
bind(fd, &localhost).expect("bind");
let ss: SockaddrStorage = getsockname(fd).expect("getsockname");
assert_eq!(&localhost, ss.as_sockaddr_in().unwrap());

Trait Implementations

impl Clone for SockaddrStorage

fn clone(&self) -> SockaddrStorage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SockaddrStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SockaddrStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<SocketAddr> for SockaddrStorage

fn from(s: SocketAddr) -> Self

Converts to this type from the input type.

impl From<SocketAddrV4> for SockaddrStorage

fn from(s: SocketAddrV4) -> Self

Converts to this type from the input type.

impl From<SocketAddrV6> for SockaddrStorage

fn from(s: SocketAddrV6) -> Self

impl Hash for SockaddrStorage

fn hash<H: Hasher>(&self, s: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SockaddrStorage

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SockaddrLike for SockaddrStorage

unsafe fn from_raw(addr: *const sockaddr, l: Option<socklen_t>) -> Option<Self>

where Self: Sized,

Unsafe constructor from a variable length source

fn len(&self) -> socklen_t

Return the length of valid data in the sockaddr structure.

fn as_ptr(&self) -> *const sockaddr

Returns a raw pointer to the inner structure. Useful for FFI.

fn family(&self) -> Option<AddressFamily>

Return the address family of this socket

fn size() -> socklen_t

where Self: Sized,

Return the available space in the structure
