Struct Udp

pub struct Udp { /* private fields */ }

The User Datagram Protocol.

Examples

In this example, Create a UDP client socket and send to an endpoint.

use asyncio::{IoContext, Protocol, Endpoint};
use asyncio::ip::{IpProtocol, IpAddrV4, Udp, UdpEndpoint, UdpSocket};

let ctx = &IoContext::new().unwrap();
let soc = UdpSocket::new(ctx, Udp::v4()).unwrap();

let ep = UdpEndpoint::new(IpAddrV4::loopback(), 12345);
soc.send_to("hello".as_bytes(), 0, ep).unwrap();

Examples

In this example, Creates a UDP server and receive from an endpoint.

use asyncio::{IoContext, Protocol, Endpoint};
use asyncio::ip::{IpProtocol, IpAddrV4, Udp, UdpEndpoint, UdpSocket};
use asyncio::socket_base::ReuseAddr;

let ctx = &IoContext::new().unwrap();
let ep = UdpEndpoint::new(Udp::v4(), 12345);
let soc = UdpSocket::new(ctx, ep.protocol()).unwrap();

soc.set_option(ReuseAddr::new(true)).unwrap();
soc.bind(&ep).unwrap();

let mut buf = [0; 256];
let (len, ep) = soc.receive_from(&mut buf, 0).unwrap();

Trait Implementations

impl Clone for Udp

fn clone(&self) -> Udp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Udp

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

Formats the value using the given formatter.

impl IpProtocol for Udp

fn v4() -> Udp

Represents a UDP for IPv4.

Examples

use asyncio::Endpoint;
use asyncio::ip::{IpProtocol, IpAddrV4, Udp, UdpEndpoint};

let ep = UdpEndpoint::new(IpAddrV4::any(), 0);
assert_eq!(Udp::v4(), ep.protocol());

fn v6() -> Udp

Represents a UDP for IPv6.

Examples

use asyncio::Endpoint;
use asyncio::ip::{IpProtocol, IpAddrV6, Udp, UdpEndpoint};

let ep = UdpEndpoint::new(IpAddrV6::any(), 0);
assert_eq!(Udp::v6(), ep.protocol());

fn is_v4(&self) -> bool

fn is_v6(&self) -> bool

impl Ord for Udp

fn cmp(&self, other: &Udp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Udp

fn eq(&self, other: &Udp) -> 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 PartialOrd for Udp

fn partial_cmp(&self, other: &Udp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Protocol for Udp

type Endpoint = IpEndpoint<Udp>

fn family_type(&self) -> i32

Reurns a value suitable for passing as the domain argument.

fn socket_type(&self) -> i32

Returns a value suitable for passing as the type argument.

fn protocol_type(&self) -> i32

Returns a value suitable for passing as the protocol argument.

unsafe fn uninitialized(&self) -> Self::Endpoint
