The possible failures of dialing.

Variants

Banned

The peer is currently banned.

ConnectionLimit(ConnectionLimit)

The configured limit for simultaneous outgoing connections has been reached.

LocalPeerId

The peer being dialed is the local peer and thus the dial was aborted.

NoAddresses

NetworkBehaviour::addresses_of_peer returned no addresses for the peer to dial.

DialPeerConditionFalse(PeerCondition)

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

Aborted

Pending connection attempt has been aborted.

InvalidPeerId(Multihash)

The provided peer identity is invalid.

WrongPeerId

Fields

obtained: PeerId

endpoint: ConnectedPoint

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

ConnectionIo(Error)

An I/O error occurred on the connection.

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 backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<PendingConnectionError<Vec<(Multiaddr, TransportError<Error>), Global>>> for DialError

fn from(error: PendingOutboundConnectionError<Error>) -> Self

Converts to this type from the input type.
