Enum DaemonError 

pub enum DaemonError {
    NotReady,
    ShuttingDown,
    FactoryAlreadyRegistered(String),
    FactoryNotFound(String),
    SnapshotIdentityMismatch {
        snapshot: u64,
        identity: u64,
    },
    Core(CoreDaemonError),
    Migration(MigrationError),
    MigrationFailed(MigrationFailureReason),
}

Errors from the SDK daemon runtime.

Variants

NotReady

start() has not been called yet; the runtime is still in Registering and will not accept spawns or migrations.

ShuttingDown

shutdown() has been called; the runtime is permanently non-functional.

FactoryAlreadyRegistered(String)

Two register_factory calls used the same kind string.

FactoryNotFound(String)

spawn / spawn_from_snapshot referenced an unregistered kind.

SnapshotIdentityMismatch

The snapshot’s entity_id.origin_hash does not match the identity handed to spawn_from_snapshot.

Fields

snapshot: u64

identity: u64

Core(CoreDaemonError)

Pass-through for errors surfaced by the core compute layer.

Migration(MigrationError)

Pass-through for migration-layer errors.

MigrationFailed(MigrationFailureReason)

Structured failure reason surfaced by the migration dispatcher on the source side. Use MigrationFailureReason::is_retriable to decide whether the caller should back off and retry rather than propagating.

Trait Implementations

impl Debug for DaemonError

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

Formats the value using the given formatter.

impl Display for DaemonError

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

Formats the value using the given formatter.

impl Error for DaemonError

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.
