Why opening the client store, releasing a send, or posting a routine failed. The seal key and the device bearer are never included.

Variants

EmptySession

No session id, so there is nothing to hash.

StoreRoot

STORE_ROOT_ENV is unset outside tests.

HomeserverUrl

HOMESERVER_URL_ENV and toml homeserver_url are both unset.

BotName

BOT_NAME_ENV is unset. The display name is required for a web session.

Nick

The display name did not yield a nick.

SessionList(String)

The host’s session list was missing or refused. No bearer is included.

Register(String)

Homeserver register failed. The text is a status and errcode, not a bearer.

UnknownNick

No session nick matched.

Dm

A direct room was not opened or its encrypted send did not finish.

Config(String)

Toml for the homeserver URL could not be read.

DeviceToken

The bearer is empty or not a single header value.

BaseUrl

base_url is not an http or https origin.

BadRecordKey

A record key tried to leave the store directory.

RoutineUrl

The routine URL is not an http or https URL this shell can post to.

NodeRoutine

Node CLI open path saw a routine URL or bearer. The value is not included.

Gateway(String)

The local gateway did not yield a routine. No token, URL, or key.

RoutineBearer

The routine bearer is not a single header value. The value is not included.

RoutineStatus(u16)

The routine answered once and was not a success. The body is not included.

RoutineTransport(String)

The routine socket or TLS handshake failed. The body is not included.

Http(String)

A homeserver call failed before a status line. The body is not included.

Ingest(String)

The engine rejected a successful HTTP body. Long blobs are omitted.

Io(Error)

Reading or writing the store directory failed.

Store(StoreError)

The seal did not authenticate. A different session id produces this.

Messenger(MessengerError)

The engine rejected the command or could not load the Olm account.

Trait Implementations

impl Debug for ShellError

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

Formats the value using the given formatter.

impl Display for ShellError

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

Formats the value using the given formatter.

impl Error for ShellError

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
