Enum MegolmError

pub enum MegolmError {
    EventError(EventError),
    JsonError(Error),
    MissingRoomKey(Option<WithheldCode>),
    MismatchedIdentityKeys(MismatchedIdentityKeysError),
    Decode(DecodeError),
    Decryption(DecryptionError),
    Store(CryptoStoreError),
    SenderIdentityNotTrusted(VerificationLevel),
}

Available on crate feature e2e-encryption only.

Error representing a failure during a group encryption operation.

Variants

EventError(EventError)

The event that should have been decrypted is malformed.

JsonError(Error)

The received decrypted event couldn’t be deserialized.

MissingRoomKey(Option<WithheldCode>)

Decryption failed because we’re missing the room key that was used to encrypt the event.

MismatchedIdentityKeys(MismatchedIdentityKeysError)

Decryption failed because of a mismatch between the identity keys of the device we received the room key from and the identity keys recorded in the plaintext of the room key to-device message.

Decode(DecodeError)

The encrypted megolm message couldn’t be decoded.

Decryption(DecryptionError)

The event could not have been decrypted.

Store(CryptoStoreError)

The storage layer returned an error.

SenderIdentityNotTrusted(VerificationLevel)

An encrypted message wasn’t decrypted, because the sender’s cross-signing identity did not satisfy the requested crate::TrustRequirement.

The nested value is the sender’s current verification level.

Trait Implementations

impl Debug for MegolmError

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