Enum vodozemac::olm::SessionCreationError

pub enum SessionCreationError {
    MissingOneTimeKey,
    MismatchedIdentityKey,
    Decryption(DecryptionError),
}

Error describing failure modes when creating a Olm Session from an incoming Olm message.

Variants

MissingOneTimeKey

The pre-key message contained an unknown one-time key. This happens either because we never had such a one-time key, or because it has already been used up.

MismatchedIdentityKey

The pre-key message contains a curve25519 identity key that doesn’t match to the identity key that was given.

Decryption(DecryptionError)

The pre-key message that was used to establish the Session couldn’t be decrypted. The message needs to be decryptable, otherwise we will have created a Session that wasn’t used to encrypt the pre-key message.
