Struct s2n_quic_core::transport::error::Error

pub struct Error {

    pub reason: &'static str,
}

Transport Errors are 62-bit unsigned integer values indicating a QUIC transport error has occurred, as defined in QUIC Transport RFC.

Fields

code: Code

A 62-bit unsigned integer value indicating the error that occurred

frame_type: VarInt

If this error was caused by a particular QUIC frame, frame_type will contain the Frame Type as defined in QUIC Transport RFC.

reason: &'static str

Additional information about the error that occurred

Implementations

impl Error

pub const fn new(code: VarInt) -> Self

impl Error

pub const NO_ERROR: Self = _

The endpoint encountered an internal error and cannot continue with the connection.

pub const CONNECTION_REFUSED: Self = _

The server refused to accept a new connection.

pub const FLOW_CONTROL_ERROR: Self = _

pub const STREAM_LIMIT_ERROR: Self = _

An endpoint received a frame for a stream identifier that exceeded its advertised stream limit for the corresponding stream type.

pub const STREAM_STATE_ERROR: Self = _

An endpoint received a frame for a stream that was not in a state that permitted that frame.

pub const FINAL_SIZE_ERROR: Self = _

An endpoint received a STREAM frame containing data that exceeded the previously established final size.

pub const FRAME_ENCODING_ERROR: Self = _

An endpoint received a frame that was badly formatted.

pub const TRANSPORT_PARAMETER_ERROR: Self = _

An endpoint received transport parameters that were badly formatted.

pub const CONNECTION_ID_LIMIT_ERROR: Self = _

The number of connection IDs provided by the peer exceeds the advertised active_connection_id_limit.

pub const PROTOCOL_VIOLATION: Self = _

An endpoint detected an error with protocol compliance that was not covered by more specific error codes.

pub const INVALID_TOKEN: Self = _

A server received a client Initial that contained an invalid Token field.

pub const APPLICATION_ERROR: Self = _

The application or application protocol caused the connection to be closed.

pub const CRYPTO_BUFFER_EXCEEDED: Self = _

An endpoint has received more data in CRYPTO frames than it can buffer.

pub const KEY_UPDATE_ERROR: Self = _

An endpoint detected errors in performing key updates.

pub const AEAD_LIMIT_REACHED: Self = _

An endpoint has reached the confidentiality or integrity limit for the AEAD algorithm used by the given connection.

pub fn description(&self) -> Option<&'static str>

impl Error

pub const fn crypto_error(code: u8) -> Self

Creates a crypto-level TransportError from a TLS alert code.

pub fn try_into_tls_error(self) -> Option<Error>

If the Error contains a tls::Error, it is returned

impl Error

pub const fn application_error(code: VarInt) -> Self

Creates an application-level Error

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

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<DecoderError> for Error

Implements conversion from decoder errors

fn from(decoder_error: DecoderError) -> Self

Converts to this type from the input type.

impl<'a> From<Error> for ConnectionClose<'a>

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Implements conversion from TLS errors See Error::crypto_error for more details

fn from(tls_error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ProcessingError

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
