Errors arising from AVC operations.

Every variant carries enough context to diagnose the failure without access to the source code. Validation denials are not errors — they flow through AvcDecision::Deny with reason codes. Errors here cover structural, cryptographic, and registry failures.

Variants

Serialization

Canonical CBOR encoding for an AVC payload failed.

Fields

reason: String

EmptyField

Required string field was empty after trimming.

Fields

field: &'static str

UnsupportedSchema

Schema version is not supported by this binary.

Fields

got: u16

supported: u16

UnsupportedProtocol

Protocol version is outside the supported compatibility range.

Fields

got: u16

min_supported: u16

max_supported: u16

BasisPointOutOfRange

A basis point value was outside the legal 0..=10_000 range.

Fields

field: &'static str

value: u32

InvalidTimestamp

A timestamp invariant was violated (e.g. expired-on-issue).

Fields

reason: String

DelegationWidens

Delegation widened scope of any kind.

Fields

dimension: &'static str

DelegationRejected

Delegation chain was rejected for a non-widening structural reason.

Fields

reason: String

Registry

Registry write conflict (e.g. duplicate revocation or unknown key).

Fields

reason: String

InvalidInput

Invalid input was supplied to a public function.

Fields

reason: String

Trait Implementations

impl Clone for AvcError

fn clone(&self) -> AvcError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AvcError

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

Formats the value using the given formatter.

impl Display for AvcError

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

Formats the value using the given formatter.

impl Eq for AvcError

impl Error for AvcError

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<T> From<Error<T>> for AvcError

fn from(_: Error<T>) -> Self

Converts to this type from the input type.

impl<T> From<Error<T>> for AvcError

fn from(_: Error<T>) -> Self

Converts to this type from the input type.

impl From<ExoError> for AvcError

fn from(value: ExoError) -> Self

Converts to this type from the input type.

impl PartialEq for AvcError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
