A structural, trust, policy, or cryptographic access failure.

Variants

Truncated

The input ended before the object did.

TrailingBytes

The object has bytes after its canonical end.

UnsupportedVersion(u16)

The object uses an unsupported version.

WrongObjectType

The encoded object tag does not match the requested type.

InvalidIdentifier

An identifier is empty or exceeds the configured bound.

InvalidUtf8

An encoded identifier is not UTF-8.

LengthLimit(usize)

A length exceeds the configured bound.

InvalidEpoch

An epoch or monotonic revision is zero or otherwise invalid.

InvalidKeyIdentity

A key does not match its domain-separated identifier or is unusable.

NonCanonicalEncoding

Re-encoding did not reproduce the original bytes.

DuplicateRule

A capability kind/name pair appears more than once.

InvalidSignature

A signature is malformed or does not verify.

UntrustedIssuer

The object was not issued by the caller’s pinned issuer.

SubjectMismatch

The object belongs to a different tenant, subject, or scope.

NotYetValid

The signed object is not active yet.

Expired

The signed object has expired.

StaleRevision

A monotonic policy or revocation revision is below the required floor.

Revoked

An authorization or key epoch has been revoked.

InvalidPermissions

A grant contains no permissions or unknown permission bits.

CryptographicFailure

HPKE sealing or opening failed without exposing a decryption oracle.

Trait Implementations

impl Clone for AccessError

fn clone(&self) -> AccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessError

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

Formats the value using the given formatter.

impl Display for AccessError

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

Formats the value using the given formatter.

impl Eq for AccessError

impl Error for AccessError

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 AccessError

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

Equality operator ==.

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

Inequality operator !=.
