Enum libp2p_request_response::OutboundFailure

pub enum OutboundFailure {
    DialFailure,
    Timeout,
    ConnectionClosed,
    UnsupportedProtocols,
}

Possible failures occurring in the context of sending an outbound request and receiving the response.

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.
