Message encoding errors.

Variants

ReadFailure(Error)

IO error when reading a field value

HeaderDecodeFailure(HeaderDecodeError)

Failure to decode the STUN header section

AttributeDecodeFailure

Failure to decode a STUN attribute

Fields

source: AttributeDecodeError

transaction_id: [u8; 12]

STUN transaction id.

IntegrityKeyGenerationFailure(IntegrityKeyGenerationError)

Failure to generate an integrity verification key

IncorrectFingerprintAttributePosition

Fingerprint attribute is not the last one. This can mean that either the provided byte data contains more than only the STUN message, or message integrity has been compromised.

Fields

msg_len: usize

STUN message length

attr_pos: usize

Fingerprint attribute position in that message

FingerprintMismatch

Stored and calculated fingerprints mismatch. Means that the message integrity has been compromised.

Fields

attr_value: u32

Provided CRC32 value

computed_value: u32

Computed CRC32 value

MessageIntegrityFail

The calculated HMAC value doesn’t match with the provided one. Either the provided integrity_key is incorrect or the message integrity has been compromised.

Fields

attr_value: Vec<u8>

Provided HMAC

computed_value: Vec<u8>

Calculated HMAC

Trait Implementations

impl Debug for MessageDecodeError

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

Formats the value using the given formatter.

impl Display for MessageDecodeError

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

Formats the value using the given formatter.

impl Error for MessageDecodeError

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.

impl From<Error> for MessageDecodeError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<HeaderDecodeError> for MessageDecodeError

fn from(source: HeaderDecodeError) -> Self

Converts to this type from the input type.
