Errors from the Node API.

Variants

PeerNotFound(String)

The requested peer is not known.

AmbiguousPeer

The query matched more than one peer (RFC 022 mesh.peer).

Fields

query: String

Original query string.

candidates: Vec<String>

Candidate display labels / routing keys for the UI.

PeerGone(String)

The peer handle is no longer usable (left the mesh).

ConnectionFailed(String)

Failed to establish a connection.

SendFailed(String)

Failed to send a message.

Envelope(EnvelopeError)

Envelope encoding/decoding error.

Session(SessionError)

Session layer error.

Network(NetworkError)

Network layer error.

Transport(TransportError)

Transport layer error.

NotImplemented(String)

The requested feature is not yet implemented.

ReservedPort(u16)

The port is reserved by truffle’s own listeners.

Stopped

The node has been stopped.

BuildError(String)

Builder configuration error.

Io(Error)

I/O error from the builder (state dir creation, device-id persistence).

Trait Implementations

impl Debug for NodeError

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

Formats the value using the given formatter.

impl Display for NodeError

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

Formats the value using the given formatter.

impl Error for NodeError

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.
