Fail-closed classification failure.

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.

RootFailed

One or both root lookups failed. A nonfailed root’s successful disposition is retained without its validated plan or absence proof.

Fields

hns: RootResolutionState

Bounded HNS lookup state.

icann: RootResolutionState

Bounded ICANN lookup state.

RootPositionMismatch

Evidence was supplied in the wrong root position.

Fields

expected: Namespace

Root required by the input slot.

actual: Namespace

Root carried by the evidence.

QueryMismatch

Evidence belongs to another scheme, hostname, port, or protocol capability set.

Fields

namespace: Namespace

Root whose complete origin query mismatched.

StaleEvidence

Presence or authenticated-absence evidence is outside its validity interval.

Fields

namespace: Namespace

Root whose evidence is stale or not yet valid.

SelectedNamespaceUnavailable

A pin or persistent binding names a root that is authentically absent. Callers must perform an explicit state-isolated namespace switch rather than silently selecting the other root.

Fields

namespace: Namespace

Bound namespace that is unavailable.

selection_reason: SelectionReason

Whether the unavailable selection came from a pin or binding.

DivergenceRequiresSelection

Both roots differ and policy requires an explicit selection.

Trait Implementations

impl Clone for ClassificationError

fn clone(&self) -> ClassificationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClassificationError

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

Formats the value using the given formatter.

impl Display for ClassificationError

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

Formats the value using the given formatter.

impl Eq for ClassificationError

impl Error for ClassificationError

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 PartialEq for ClassificationError

fn eq(&self, other: &ClassificationError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
