Struct Transport

pub struct Transport<T>
where
    T: Provider + Send,
{ /* private fields */ }

Available on crate feature tcp only.

An abstract libp2p_core::Transport implementation.

You shouldn’t need to use this type directly. Use one of the following instead:

• tokio::Transport
• async_io::Transport

Implementations

impl<T> Transport<T>

where T: Provider + Send,

pub fn new(config: Config) -> Transport<T>

Create a new instance of Transport.

If you don’t want to specify a Config, use Transport::default.

It is best to call this function through one of the type-aliases of this type:

• tokio::Transport::new
• async_io::Transport::new

Trait Implementations

impl<T> Default for Transport<T>

where T: Provider + Send,

fn default() -> Transport<T>

Creates a Transport with reasonable defaults.

This transport will have port-reuse disabled.

impl<T> Transport for Transport<T>

where T: Provider + Send + 'static, <T as Provider>::Listener: Unpin, <T as Provider>::Stream: Unpin,

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

Poll all listeners.

type Output = <T as Provider>::Stream

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

type Error = Error

An error that occurred during connection setup.

type Dial = Pin<Box<dyn Future<Output = Result<<Transport<T> as Transport>::Output, <Transport<T> as Transport>::Error>> + Send>>

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

type ListenerUpgrade = Ready<Result<<Transport<T> as Transport>::Output, <Transport<T> as Transport>::Error>>

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

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

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

fn boxed(self) -> Boxed<Self::Output>

where Self: Sized + Send + Unpin + 'static, Self::Dial: Send + 'static, Self::ListenerUpgrade: Send + 'static, Self::Error: Send + Sync,

Boxes the transport, including custom transport errors.

fn map<F, O>(self, f: F) -> Map<Self, F>

where Self: Sized, F: FnOnce(Self::Output, ConnectedPoint) -> O,

Applies a function on the connections created by the transport.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F>

where Self: Sized, F: FnOnce(Self::Error) -> E,

Applies a function on the errors generated by the futures of the transport.

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.

fn and_then<C, F, O>(self, f: C) -> AndThen<Self, C>

where Self: Sized, C: FnOnce(Self::Output, ConnectedPoint) -> F, F: TryFuture<Ok = O>, <F as TryFuture>::Error: Error + 'static,

Applies a function producing an asynchronous result to every connection created by this transport.

fn upgrade(self, version: Version) -> Builder<Self>

where Self: Sized, Self::Error: 'static,

Begins a series of protocol upgrades via an upgrade::Builder.
