Enum Error

pub enum Error<C: Connector, E: Debug> {
    Open(C::OpenError),
    Send(C::SendError),
    Recv(C::RecvError),
    EarlyClose,
    Downcast,
    Application(E),
}

Server error when accepting a server streaming request

This combines network errors with application errors. Usually you don’t care about the exact nature of the error, but if you want to handle application errors differently, you can match on this enum.

Variants

Open(C::OpenError)

Unable to open a substream at all

Send(C::SendError)

Unable to send the request to the server

Recv(C::RecvError)

Error received when creating the stream

EarlyClose

Connection was closed before receiving the first message

Downcast

Unexpected response from the server

Application(E)

Application error

Trait Implementations

impl<C: Debug + Connector, E: Debug + Debug> Debug for Error<C, E>

where C::OpenError: Debug, C::SendError: Debug, C::RecvError: Debug,

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

Formats the value using the given formatter.

impl<S: Connector, E: Debug> Display for Error<S, E>

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

Formats the value using the given formatter.

impl<S: Connector, E: Debug> Error for Error<S, E>

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>)
