Expand description

Error type describing the different ways message decoding can fail.

Variants

`MessageType(usize)`

The Olm message has an invalid type.

`MissingVersion`

The message is missing a valid version.

`MessageTooShort(usize)`

The message doesn’t have enough data to be correctly decoded.

`InvalidVersion(u8, u8)`

The message has a unsupported version.

`InvalidKey(KeyError)`

An embedded public key couldn’t be decoded.

`InvalidMacLength(usize, usize)`

The embedded message authentication code couldn’t be decoded.

`Signature(SignatureError)`

An embedded signature couldn’t be decoded.

`ProtoBufError(DecodeError)`

The message couldn’t be decoded as a valid protocol buffer message.

`Base64(DecodeError)`

The message wasn’t valid base64.
