Enum Error 

#[non_exhaustive]
pub enum Error {
    ConnectionClosed,
    ConnectionClosing,
    InvalidConnection,
    Connect(ConnectError),
    Connection(ConnectionError),
    Write(WriteError),
    Read(ReadError),
    Readable(ReadableError),
    StreamClosed,

}

Errors returned by ringline-quic operations.

Marked #[non_exhaustive] because the crate is still evolving and new transport-layer error kinds are expected. Downstream match blocks must include a wildcard arm.

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.

ConnectionClosed

ConnectionClosing

The connection has been locally closed but quinn-proto is still in its draining window — distinguished from ConnectionClosed so callers don’t retry sends in a tight loop.

InvalidConnection

Connect(ConnectError)

Connection(ConnectionError)

Write(WriteError)

Read(ReadError)

Readable(ReadableError)

StreamClosed

Operation targeted a stream that has already been finished, reset, or stopped. Distinguished from connection-level closure so callers can surface stream-scoped errors without tearing the connection.

StreamStopped(VarInt)

Peer issued STOP_SENDING with the given application error code. Surfaced from stream_finish (and any future send that races the STOP) so the caller learns the application-defined reason.

DatagramDisabled

Datagrams are disabled by local transport config — sends will never succeed on this connection.

DatagramUnsupportedByPeer

Datagrams are disabled by the peer — sends will never succeed on this connection.

DatagramTooLarge

Datagram payload exceeded the peer’s max_datagram_size. Caller must split or shrink.

DatagramBlocked(Bytes)

The outgoing datagram buffer is full. Bytes carries back the caller’s original payload so it can be re-sent on the next QuicEvent::DatagramsUnblocked without re-allocating.

Io(Error)

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, __formatter: &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>)
