Possible errors of a STUN/TURN Server.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MaxRetriesExceeded

Failed to allocate new relay connection, since maximum retires count exceeded.

PeerAddressFamilyMismatch

{eer address is part of a different address family than that of the relayed transport address of the allocation.

Closed

Error when trying to perform action after closing server.

SameChannelDifferentPeer

Channel binding request failed, since channel number is currently bound to a different transport address.

SamePeerDifferentChannel

Channel binding request failed, since the transport address is currently bound to a different channel number.

LifetimeZero

Cannot create allocation with zero lifetime.

DupeFiveTuple

Cannot create allocation for the same five-tuple.

NoSuchUser

Authentication error.

UnexpectedClass

Unsupported request class.

RelayAlreadyAllocatedForFiveTuple

Allocation request failed, since allocation already exists for the provided FiveTuple.

AttributeNotFound

STUN message doesn’t have a required attribute.

IntegrityMismatch

STUN message contains wrong MessageIntegrity.

NoDontFragmentSupport

DONT-FRAGMENT attribute is not supported.

RequestWithReservationTokenAndEvenPort

Allocation request cannot have both RESERVATION-TOKEN and EVEN-PORT.

RequestWithReservationTokenAndReqAddressFamily

Allocation request cannot contain both RESERVATION-TOKEN and REQUESTED-ADDRESS-FAMILY.

NoAllocationFound

No allocation for the provided FiveTuple.

UnsupportedRelayProto

The specified protocol is not supported.

NoPermission

Failed to handle Send Indication, since there is no permission for the provided address.

NoSuchChannelBind

Failed to handle channel data, since there is no binding for the provided channel.

Encode(ErrorKind)

Failed to encode message.

Transport(Error)

Failed to send message.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Error

impl StructuralPartialEq for Error
