Protocol errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotStarted

Protocol not started.

AlreadyStarted

Protocol already started.

InvalidConfiguration(String)

Invalid configuration.

Core(Error)

Core error.

Transport(Error)

Transport error.

Router(Error)

Router error.

Reliability(Error)

Reliability error.

Mls(MlsError)

MLS error.

MlsNotInitialized

MLS not initialized.

NoKeyPackage(String)

No key package available for recipient.

SessionNotReady(EstablishmentState)

Session not ready; establishment in progress. Caller can retry or show “Establishing…”.

EncryptFailed(String)

Outbound message encryption failed.

Service(ServiceError)

Service error.

Serialization(String)

Serialization error.

UserBlocked(String)

Operation rejected because the target user is blocked.

MediaTransferLimit(String)

Too many concurrent media transfers to the same recipient. Encrypted transfers share the recipient’s session ratchet, whose out-of-order tolerance bounds how many chunks may be in flight at once.

GroupNotFound(String)

Group does not exist locally.

PermissionDenied(String)

Operation requires a group role or permission the caller does not hold.

InvalidState(String)

Operation rejected by the current group or protocol state (e.g. last-admin constraints, member limits, expired key packages).

InvalidArgument(String)

A caller-supplied argument failed validation.

Other(String)

Generic error.

Trait Implementations

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 Error for Error

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

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