Struct libp2p_core::transport::Boxed

pub struct Boxed<O> { /* fields omitted */ }

A Boxed transport is a Transport whose Dial, Listener and ListenerUpgrade futures are Boxed and only the Output and Error types are captured in type variables.

Trait Implementations

impl<O> Clone for Boxed<O>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<O> Debug for Boxed<O>

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

Formats the value using the given formatter.

impl<O> Transport for Boxed<O>

type Output = O

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

type Error = Error

An error that occurred during connection setup.

type Listener = Pin<Box<dyn Stream<Item = Result<ListenerEvent<Pin<Box<dyn Future<Output = Result<O>> + Send>>, Error>>> + Send>>

A stream of Outputs for inbound connections.

type ListenerUpgrade = Pin<Box<dyn Future<Output = Result<O>> + Send>>

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

type Dial = Pin<Box<dyn Future<Output = Result<O>> + Send>>

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

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

Listens on the given Multiaddr, producing a stream of pending, inbound connections and addresses this transport is listening on (cf. ListenerEvent).

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

Dials the given Multiaddr, returning a future for a pending outbound 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 boxed(self) -> Boxed<Self::Output> where
    Self: Transport + Sized + Clone + Send + Sync + 'static,
    Self::Dial: Send + 'static,
    Self::Listener: 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 + Clone, 

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 + Clone, 

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 + Clone,
    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.
