Enum DecodeError

pub enum DecodeError {
    MessageType(usize),
    MissingVersion,
    MessageTooShort(usize),
    InvalidVersion(u8, u8),
    InvalidKey(KeyError),
    InvalidMacLength(usize, usize),

}

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(ProtoBufDecodeError)

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

Base64(Base64DecodeError)

The message wasn’t valid base64.

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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.
