Enum KernelError 

pub enum KernelError {
    EventStoreBoot(BootError),
    CacheReplay(CacheReplayError),
    EventStoreHalted(HaltReason),
}

Typed error surfaced when the event store fails the run lifecycle.

Wraps the boot-time and shutdown-time failure modes so a kernel caller can react to a fail-stop without inspecting individual writer/backend errors.

Variants

EventStoreBoot(BootError)

The event-store boot path failed.

CacheReplay(CacheReplayError)

Cache state reconstruction from a recovered event-store run failed.

EventStoreHalted(HaltReason)

The writer signaled fail-stop after the kernel was already started.

Trait Implementations

impl Debug for KernelError

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

Formats the value using the given formatter.

impl Display for KernelError

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

Formats the value using the given formatter.

impl Error for KernelError

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<BootError> for KernelError

fn from(source: BootError) -> Self

Converts to this type from the input type.

impl From<CacheReplayError> for KernelError

fn from(source: CacheReplayError) -> Self

Converts to this type from the input type.
