Enum RequestResponseError 

pub enum RequestResponseError {
    DialFailure,
    Timeout,
    ConnectionClosed,
    UnsupportedProtocols,
    Io(Error),
}

Libp2p request response outbound error type. This indicates a failure sending a request to a peer. This is different from a failure response from a node, as this is an error that prevented a response.

This type mirrors the internal libp2p type, but this avoids having to expose that internal type.

Variants

DialFailure

The request could not be sent because a dialing attempt failed.

Timeout

The request timed out before a response was received.

It is not known whether the request may have been received (and processed) by the remote peer.

ConnectionClosed

The connection closed before a response was received.

It is not known whether the request may have been received (and processed) by the remote peer.

UnsupportedProtocols

The remote supports none of the requested protocols.

Io(Error)

An IO failure happened on an outbound stream.

Trait Implementations

impl Debug for RequestResponseError

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

Formats the value using the given formatter.

impl Display for RequestResponseError

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

Formats the value using the given formatter.

impl Error for RequestResponseError

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<OutboundFailure> for RequestResponseError

fn from(err: OutboundFailure) -> Self

Converts to this type from the input type.
