Struct cap_std::os::unix::net::UnixDatagram

source ·
pub struct UnixDatagram { /* private fields */ }
Expand description

A Unix datagram socket.

This corresponds to std::os::unix::net::UnixDatagram.

This UnixDatagram has no bind, connect, or send_to methods. To create a UnixDatagram, first obtain a Dir containing the path, and then call Dir::bind_unix_datagram, Dir::connect_unix_datagram, or Dir::send_to_unix_datagram_addr.

Implementations§

source§

impl UnixDatagram

source

pub fn from_std(std: UnixDatagram) -> Self
