Struct ConnHandle 

pub struct ConnHandle(/* private fields */);

Stable, process-unique connection identifier.

Connections are identified by a monotonic 64-bit counter so the id stays unique across reconnects and across transports (TCP, QUIC).

Implementations

impl ConnHandle

pub fn raw(self) -> u64

Borrow the raw 64-bit id.

Examples

let listener = tokio::net::TcpListener::bind("127.0.0.1:0").await.unwrap();
let addr = listener.local_addr().unwrap();
let _accept = tokio::spawn(async move {
    let (s, _) = listener.accept().await.unwrap();
    drop(s);
});
let s = tokio::net::TcpStream::connect(addr).await.unwrap();
let transport = Box::new(TcpTransport::new(s, ConnRole::Server));
let conn = Conn::new(transport, ConnRole::Server);
assert!(conn.handle().raw() > 0);

Trait Implementations

impl Clone for ConnHandle

fn clone(&self) -> ConnHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnHandle

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

Formats the value using the given formatter.

impl Hash for ConnHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConnHandle

fn eq(&self, other: &ConnHandle) -> 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.
