impl<T: Transport> WsConfig<T>where
    T: Transport + Send + Unpin + 'static,
    T::Error: Send + 'static,
    T::Dial: Send + 'static,
    T::ListenerUpgrade: Send + 'static,

pub fn new(transport: T) -> Self

Create a new websocket transport based on the given transport.

*Note: The given transport must be based on TCP/IP and should usually incorporate DNS resolution, though the latter is not strictly necessary if one wishes to only use the Ws protocol with known IP addresses and ports. See libp2p-tcp and libp2p-dns for constructing the inner transport.

pub fn max_redirects(&self) -> u8

Return the configured maximum number of redirects.

pub fn set_max_redirects(&mut self, max: u8) -> &mut Self

Set max. number of redirects to follow.

pub fn max_data_size(&self) -> usize

Get the max. frame data size we support.

pub fn set_max_data_size(&mut self, size: usize) -> &mut Self

Set the max. frame data size we support.

pub fn set_tls_config(&mut self, c: Config) -> &mut Self

Set the TLS configuration if TLS support is desired.

pub fn use_deflate(&mut self, flag: bool) -> &mut Self

Should the deflate extension (RFC 7692) be used if supported?

type Output = RwStreamSink<BytesConnection<<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.

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

type Dial = MapFuture<Pin<Box<dyn Future<Output = Result<Connection<<T as Transport>::Output>, Error<<T as Transport>::Error>>> + Send + 'static, Global>>, fn(Connection<<T as Transport>::Output>, ConnectedPoint) -> RwStreamSink<BytesConnection<<T as Transport>::Output>>>

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

fn listen_on(
    &mut self,
    addr: Multiaddr
) -> Result<ListenerId, TransportError<Self::Error>>

Listens on the given [Multiaddr] for inbound connections.

Remove a listener.

fn dial(
    &mut self,
    addr: Multiaddr
) -> Result<Self::Dial, TransportError<Self::Error>>

fn dial_as_listener(
    &mut self,
    addr: Multiaddr
) -> Result<Self::Dial, TransportError<Self::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.
