Enum ServerError 

pub enum ServerError {
    Transport(Error),
    Consensus(ConsensusError),
    Core(CoreError),
    WatchPanic {
        payload: String,
        bt: Bt,
    },
    WatchStreamClosed,
}

Variants

Transport(Error)

Consensus(ConsensusError)

Core(CoreError)

WatchPanic

The leader-watch task panicked. Distinct from a clean error return so operators can tell “driver returned Err” (recoverable design) from “task panicked” (programming bug).

Fields

payload: String

bt: Bt

WatchStreamClosed

The consensus driver’s leadership_events() stream ended cleanly while the leader-watch task was running. The stream is contracted to live for the life of the server, so its end is anomalous (driver shutdown, lost session, etc.) — distinct from a Consensus error returned mid-fence. The watch task publishes ServingState::NotServing before returning this variant so embedders who never observe the JoinHandle still get the documented fail-safe behavior.

Trait Implementations

impl Debug for ServerError

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

Formats the value using the given formatter.

impl Display for ServerError

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

Formats the value using the given formatter.

impl Error for ServerError

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.
