Expand description

Internal representation of errors.

Variants (Non-exhaustive)

This enum is marked as 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.

`AuthenticationRequired`

Queried endpoint requires authentication but was called on an anonymous client.

`BadCryptoStoreState`

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

`StateStore(StoreError)`

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

`SerdeJson(JsonError)`

An error when (de)serializing JSON.

`IoError(IoError)`

An error representing IO errors.

`CryptoStore(CryptoStoreError)`

An error occurred in the crypto store.

`OlmError(OlmError)`

An error occurred during a E2EE operation.

`MegolmError(MegolmError)`

An error occurred during a E2EE group operation.
