Why a link or one of its operations failed.

Variants

InvalidConfig(String)

The configuration cannot be dialed: a key of another profile than the target’s, or admission limits macula would not start with.

Dial(String)

The dial failed.

Handshake(HandshakeError)

The handshake refused, or was refused.

HandshakeTimeout

The handshake did not finish within HANDSHAKE_TIMEOUT.

Issuer(IssuerError)

The issuer had no CONNECT material in force.

Io(String)

The QUIC connection or a stream failed.

FrameTooLarge(usize)

A frame longer than the cap in force.

Frame(FrameError)

A frame that could not be built, or one received that does not verify.

Record(RecordError)

A record that could not be built, or one found that does not verify.

StatusExpired

The station’s status statement lapsed past the grace.

BindingExpired

The station’s TLS binding reached its not_after.

Closed

The link was closed by its owner.

Goodbye(String)

The station ended the link with a GOODBYE, for this reason.

LivenessLost

The station missed two liveness probes in a row.

V5DowngradeRefused

A station this process completed handshake v5 with that now answers v4, or a v4 link to it that a v5 completion ended: refused, not retried, until forget_v5_peer.

CallTimeout

No verified reply answered the call within its timeout.

Provider

A provider’s ERROR for the call.

Fields

responded_by: [u8; 32]

code: String

detail: Option<String>

Relay

A relay error the connected station reported for the call.

Fields

reported_by: [u8; 32]

code: String

RecordNotFound

A find_record the station answered not_found.

UnexpectedReply(String)

A station reply to a DHT call in a shape that call never answers with.

InvalidOffer

An offer without exactly one handler, or an org procedure’s without the realm key.

NoOrg

A procedure without a namespace, which nobody can authorize.

AlreadyServed

A procedure already served on this link.

Stopped

A served procedure withdrawn by its owner.

Stream

A stream ended by a STREAM_ERROR: the peer’s, the station’s relay error (relay), or this side’s own abort.

Fields

code: String

message: String

relay: bool

EndOfStream

A stream that ended normally.

StreamClosed

A send on a stream this side has ended.

StreamOpenTooLarge(usize)

A STREAM_OPEN over the 1 MiB a peer reads of one.

Trait Implementations

impl Clone for LinkError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinkError

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

Formats the value using the given formatter.

impl Display for LinkError

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

Formats the value using the given formatter.

impl Eq for LinkError

impl Error for LinkError

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
