Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

source

impl AddressFamily

source

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.
