Possible errors when trying to establish or upgrade an outbound connection.

Variants

LocalPeerId

Fields

endpoint: ConnectedPoint

The peer identity obtained on the connection matches the local peer.

NoAddresses

No addresses have been provided by NetworkBehaviour::handle_pending_outbound_connection and DialOpts.

DialPeerConditionFalse(PeerCondition)

The provided dial_opts::PeerCondition evaluated to false and thus the dial was aborted.

Aborted

Pending connection attempt has been aborted.

WrongPeerId

Fields

obtained: PeerId

endpoint: ConnectedPoint

The peer identity obtained on the connection did not match the one that was expected.

Denied

Fields

cause: ConnectionDenied

Transport(Vec<(Multiaddr, TransportError<Error>)>)

An error occurred while negotiating the transport protocol(s) on a connection.

Trait Implementations

impl Debug for DialError

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

Formats the value using the given formatter.

impl Display for DialError

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

Formats the value using the given formatter.

impl Error for DialError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
