Enum BlockSyncOutboundError 

pub enum BlockSyncOutboundError {
    DialFailure,
    Timeout,
    ConnectionClosed,
    UnsupportedProtocols,
    Io(String),
}

Transport-level failure modes for an outbound block-sync request.

These are libp2p-layer errors (timeout, connection closed, codec failure). Server-side application errors are carried inside the BlockSyncResponse::Error variant on a successful round-trip and do NOT surface here — callers must inspect result.ok() for those.

Trait Implementations

impl Debug for BlockSyncOutboundError

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

Formats the value using the given formatter.

impl Display for BlockSyncOutboundError

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

Formats the value using the given formatter.

impl Error for BlockSyncOutboundError

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 BlockSyncOutboundError

fn from(e: OutboundFailure) -> Self

Converts to this type from the input type.
