Implementations

impl AddressFamily

pub const fn from_i32(family: i32) -> Option<AddressFamily>

Create a new AddressFamily from an integer value retrieved from libc, usually from the sa_family field of a sockaddr.

Currently only supports these address families: Unix, Inet (v4 & v6), Netlink, Link/Packet and System. Returns None for unsupported or unknown address families.

Trait Implementations

impl Clone for AddressFamily

fn clone(&self) -> AddressFamily

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddressFamily

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

Formats the value using the given formatter.

impl Hash for AddressFamily

fn hash<__H: Hasher>(&self, state: &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 AddressFamily

fn eq(&self, other: &AddressFamily) -> 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.
