Enum ArkheError 

#[non_exhaustive]
pub enum ArkheError {
    InstanceNotFound,
    CapabilityDenied,
    Domain {
        code: u32,
        payload: Bytes,
    },
}

Top-level kernel error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InstanceNotFound

Requested InstanceId is not live.

CapabilityDenied

Caller lacks one or more required capability bits.

Domain

Domain-level error. The kernel does not interpret code or payload; they are an L1/L2 protocol. Payload is canonical bytes (CanonicalEncode discipline) so cross-replay determinism holds.

Fields

code: u32

L1/L2-defined error code; kernel-opaque.

payload: Bytes

Canonical bytes carrying L1/L2-defined error payload.

Trait Implementations

impl Clone for ArkheError

fn clone(&self) -> ArkheError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArkheError

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

Formats the value using the given formatter.

impl Display for ArkheError

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

Formats the value using the given formatter.

impl Error for ArkheError

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.
