FCP parse, validation and state-machine failure.

Variants

TooLarge

The envelope exceeded a fixed allocation bound.

FieldTooLarge

A variable field exceeded its kind-specific bound.

Truncated

The envelope was truncated.

TrailingBytes

Bytes followed an otherwise complete envelope.

BadMarker

Marker did not identify the FCP wire format.

UnsupportedVersion

Version is not supported.

UnknownKind

Envelope kind is not known.

BadSenderKey

The endpoint public key did not parse strictly.

BadSignature

The Ed25519 signature did not verify.

NonCanonical

Input was not the one canonical encoding of its parsed form.

WrongFederation

Remote input did not bind to this federation.

WrongAttempt

Remote input did not bind to this attempt.

WrongSender

Remote input was not authored by the configured peer endpoint.

WrongRecipient

Remote input was not addressed to this local endpoint.

SameEndpoint

The configured local and remote endpoint keys were identical.

WrongLocalSigner

A local operation used a signer for another endpoint.

InvalidState

Operation is not permitted in the current state.

Glare

Both peers tried to offer while a local offer was outstanding.

WrongCandidateParent

Candidate did not bind to an active offer or answer.

BadConfigurationMarker

Configuration marker did not identify the FCP configuration format.

UnsupportedConfigurationVersion

Configuration version is not supported.

BadConfigurationAuthority

Configuration authority public key did not parse strictly.

WrongConfigurationAuthority

Configuration signer did not match the configuration’s pinned authority.

BadConfigurationSignature

Configuration signature did not verify.

TooManyFederationMembers

Configuration declared more than the fixed member bound.

DuplicateFederationMember

Configuration contains a duplicate CFR identity or endpoint binding.

BadPostQuantumKey

ML-DSA-65 public-key bytes did not parse as canonical FCP identity material.

BadPostQuantumSignatureEncoding

ML-DSA-65 signature encoding was not canonical.

BadPostQuantumSignature

ML-DSA-65 signature did not verify.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

Available on crate feature std only.

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 PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
