Internal representation of 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.

BadCryptoStoreState

Available on crate feature e2e-encryption only.

Attempting to restore a session after the olm-machine has already been set up fails

EncryptionNotEnabled

Available on crate feature e2e-encryption only.

The room where a group session should be shared is not encrypted.

StateStore(StoreError)

A generic error returned when the state store fails not due to IO or (de)serialization.

EventCacheStore(EventCacheStoreError)

An error happened while manipulating the event cache store.

EventCacheLock(CrossProcessLockError)

An error happened while attempting to lock the event cache store.

CryptoStore(CryptoStoreError)

Available on crate feature e2e-encryption only.

An error occurred in the crypto store.

OlmError(OlmError)

Available on crate feature e2e-encryption only.

An error occurred during a E2EE operation.

MegolmError(MegolmError)

Available on crate feature e2e-encryption only.

An error occurred during a group E2EE operation.

InvalidReceiveMembersParameters

An error caused by calling the BaseClient::receive_all_members function with invalid parameters

InsufficientData

This request failed because the local data wasn’t sufficient.

DeserializationError(Error)

There was a serde_json deserialization 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

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.
