Struct cap_std::net::UdpSocket

pub struct UdpSocket { /* private fields */ }

Available on non-WASI only.

A UDP socket.

This corresponds to std::net::UdpSocket.

This UdpSocket has no bind, connect, or send_to methods. To create a UdpSocket bound to an address or to send a message to an address, first obtain a Pool permitting the address, and then call Pool::bind_udp_socket, or Pool::connect_udp_socket, or Pool::send_to_udp_socket_addr.

Implementations

impl UdpSocket

pub fn from_std(std: UdpSocket) -> Self

Constructs a new instance of Self from the given std::net::UdpSocket.

This grants access the resources the std::net::UdpSocket instance already has access to.
