Struct Transport 

pub struct Transport<T, R> { /* private fields */ }

Available on crate feature dns only.

A Transport for performing DNS lookups when dialing Multiaddresses. You shouldn’t need to use this type directly. Use tokio::Transport instead.

Implementations

impl<T> Transport<T, Resolver<GenericConnector<TokioRuntimeProvider>>>

pub fn system( inner: T, ) -> Result<Transport<T, Resolver<GenericConnector<TokioRuntimeProvider>>>, Error>

Creates a new Transport from the OS’s DNS configuration and defaults.

pub fn custom( inner: T, cfg: ResolverConfig, opts: ResolverOpts, ) -> Transport<T, Resolver<GenericConnector<TokioRuntimeProvider>>>

Creates a Transport with a custom resolver configuration and options.

Trait Implementations

impl<T, R> Debug for Transport<T, R>

where T: Debug, R: Debug,

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

Formats the value using the given formatter.

impl<T, R> Transport for Transport<T, R>

where T: Transport + Send + Unpin + 'static, <T as Transport>::Error: Send, <T as Transport>::Dial: Send, R: Clone + Send + Sync + Resolver + 'static,

type Output = <T as Transport>::Output

The result of a connection setup process, including protocol upgrades.

type Error = Error<<T as Transport>::Error>

An error that occurred during connection setup.

type ListenerUpgrade = MapErr<<T as Transport>::ListenerUpgrade, fn(<T as Transport>::Error) -> <Transport<T, R> as Transport>::Error>

A pending Output for an inbound connection, obtained from the Transport stream.

type Dial = Either<MapErr<<T as Transport>::Dial, fn(<T as Transport>::Error) -> <Transport<T, R> as Transport>::Error>, Pin<Box<dyn Future<Output = Result<<Transport<T, R> as Transport>::Output, <Transport<T, R> as Transport>::Error>> + Send>>>

A pending Output for an outbound connection, obtained from dialing.

fn listen_on( &mut self, id: ListenerId, addr: Multiaddr, ) -> Result<(), TransportError<<Transport<T, R> as Transport>::Error>>

Listens on the given Multiaddr for inbound connections with a provided ListenerId.

fn remove_listener(&mut self, id: ListenerId) -> bool

Remove a listener.

fn dial( &mut self, addr: Multiaddr, dial_opts: DialOpts, ) -> Result<<Transport<T, R> as Transport>::Dial, TransportError<<Transport<T, R> as Transport>::Error>>

Dials the given Multiaddr, returning a future for a pending outbound connection.

fn poll( self: Pin<&mut Transport<T, R>>, cx: &mut Context<'_>, ) -> Poll<TransportEvent<<Transport<T, R> as Transport>::ListenerUpgrade, <Transport<T, R> as Transport>::Error>>

fn or_transport<U>(self, other: U) -> OrTransport<Self, U>

where Self: Sized, U: Transport, <U as Transport>::Error: 'static,

Adds a fallback transport that is used when encountering errors while establishing inbound or outbound connections.
