Enum DialError 

pub enum DialError {
    LocalPeerId {
        address: Multiaddr,
    },
    NoAddresses,
    DialPeerConditionFalse(PeerCondition),
    Aborted,
    WrongPeerId {
        obtained: PeerId,
        address: Multiaddr,
    },
    Denied {
        cause: ConnectionDenied,
    },
    Transport(Vec<(Multiaddr, TransportError<Error>)>),
}

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

Variants

LocalPeerId

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

Fields

address: Multiaddr

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

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

Fields

obtained: PeerId

address: Multiaddr

Denied

One of the NetworkBehaviours rejected the outbound connection via NetworkBehaviour::handle_pending_outbound_connection or NetworkBehaviour::handle_established_outbound_connection.

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<(), Error>

Formats the value using the given formatter.

impl Display for DialError

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

Formats the value using the given formatter.

impl Error for DialError

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

Returns 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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<PendingOutboundConnectionError> for DialError

fn from(error: PendingOutboundConnectionError) -> DialError

Converts to this type from the input type.
