Struct Tcp

pub struct Tcp { /* private fields */ }

The Transmission Control Protocol.

Examples

In this example, Create a TCP server socket and accept a connection by client.

use asyncio::{IoContext, Protocol, Endpoint};
use asyncio::ip::{IpProtocol, Tcp, TcpEndpoint, TcpSocket, TcpListener};
use asyncio::socket_base::ReuseAddr;

let ctx = &IoContext::new().unwrap();
let ep = TcpEndpoint::new(Tcp::v4(), 12345);
let soc = TcpListener::new(ctx, ep.protocol()).unwrap();

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

let (acc, ep) = soc.accept().unwrap();

Examples

In this example, Create a TCP client socket and connect to TCP server.

use asyncio::{IoContext, Protocol, Endpoint};
use asyncio::ip::{IpProtocol, IpAddrV4, Tcp, TcpEndpoint, TcpSocket};

let ctx = &IoContext::new().unwrap();
let soc = TcpSocket::new(ctx, Tcp::v4()).unwrap();

let _ = soc.connect(&TcpEndpoint::new(IpAddrV4::loopback(), 12345));

Examples

In this example, Resolve a TCP hostname and connect to TCP server.

use asyncio::{IoContext, Protocol, Endpoint};
use asyncio::ip::{Tcp, TcpEndpoint, TcpSocket, TcpResolver};

let ctx = &IoContext::new().unwrap();
let re = TcpResolver::new(ctx);
let (soc, ep) = re.connect(("localhost", "12345")).unwrap();

Trait Implementations

impl Clone for Tcp

fn clone(&self) -> Tcp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tcp

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

Formats the value using the given formatter.

impl GetSocketOption<Tcp> for NoDelay

fn data_mut(&mut self) -> &mut Self::Data

fn capacity(&self) -> usize

fn resize(&mut self, _size: usize)

impl IpProtocol for Tcp

fn v4() -> Tcp

Represents a TCP for IPv4.

Examples

use asyncio::Endpoint;
use asyncio::ip::{IpProtocol, IpAddrV4, Tcp, TcpEndpoint};

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

fn v6() -> Tcp

Represents a TCP for IPv6.

Examples

use asyncio::Endpoint;
use asyncio::ip::{IpProtocol, IpAddrV6, Tcp, TcpEndpoint};

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

fn is_v4(&self) -> bool

fn is_v6(&self) -> bool

impl Ord for Tcp

fn cmp(&self, other: &Tcp) -> 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 Tcp

fn eq(&self, other: &Tcp) -> 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 Tcp

fn partial_cmp(&self, other: &Tcp) -> 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.

type Endpoint = IpEndpoint<Tcp>

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.
