Struct libp2p::wasm_ext::ExtTransport

pub struct ExtTransport { /* private fields */ }

Implementation of Transport whose implementation is handled by some FFI.

Implementations

impl ExtTransport

pub fn new(transport: Transport) -> ExtTransport

Creates a new ExtTransport that uses the given external Transport.

Trait Implementations

impl Debug for ExtTransport

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

Formats the value using the given formatter.

impl Transport for ExtTransport

type Output = Connection

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

type Error = JsErr

An error that occurred during connection setup.

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

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

type Dial = Dial

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

fn listen_on( &mut self, listener_id: ListenerId, addr: Multiaddr, ) -> Result<(), TransportError<<ExtTransport 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, ) -> Result<<ExtTransport as Transport>::Dial, TransportError<<ExtTransport as Transport>::Error>>

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

fn dial_as_listener( &mut self, addr: Multiaddr, ) -> Result<<ExtTransport as Transport>::Dial, TransportError<<ExtTransport as Transport>::Error>>

As Transport::dial but has the local node act as a listener on the outgoing connection.

fn address_translation( &self, _server: &Multiaddr, _observed: &Multiaddr, ) -> Option<Multiaddr>

Performs a transport-specific mapping of an address observed by a remote onto a local listen address to yield an address for the local node that may be reachable for other peers.

fn poll( self: Pin<&mut ExtTransport>, cx: &mut Context<'_>, ) -> Poll<TransportEvent<<ExtTransport as Transport>::ListenerUpgrade, <ExtTransport as Transport>::Error>>

Poll for TransportEvents.

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.
