OTRError is the enum containing the various errors that can occur.

Variants

ProtocolViolation(&'static str)

Message contained invalid data according to the OTR protocol.

IncompleteMessage

Message payload is incomplete. The message cannot be reconstructed from the received bytes.

UnreadableMessage(InstanceTag)

Encrypted message is unreadable due to loss of keys and/or wrong protocol state.

MessageForOtherInstance

An OTR message was received that is intended for a different instance (client).

UnknownInstance(InstanceTag)

Message to be sent to an unknown instance.

UnsupportedVersion(u16)

Unsupported version encountered.

IncorrectState(&'static str)

Messaging is blocked in OTR protocol “Finished” state to ensure no accidental disclosure occurs.

CryptographicViolation(CryptoError)

Violation of cryptographic or mathematical requirement for correct/secure operation.

PolicyRestriction(&'static str)

PolicyRestriction indicates an error caused by the active policy.

AuthenticationError(AKEError)

(AKE) AuthenticationError indicates that there was an error during AKE.

SMPInProgress

SMPInProgress indicates that an SMP exchange is in progress, so to initiate a new SMP, the previous one needs to be aborted first.

SMPSuccess(Option<TLV>)

SMPSuccess indicates successful finishing SMP without a follow-up TLV needing to be sent.

SMPFailed(Option<TLV>)

SMPFailed indicates a unsuccessfully completed SMP.

SMPAborted(bool)

SMPAborted indicates SMP process was aborted, most likely by user request. Provided TLV can be sent to other party to signal SMP abort. The boolean value indicates whether the abort-action needs to be communicated, that is: true to require sending abort-TLV, false if no further action needed.

UserError(&'static str)

UserError indicates a user error, with a description provided in the tuple.
