}

A named refusal at a token, key or live-contract boundary.

Variants

WrongAudience

The signed audience differs from the product.

WrongIssuer

The signed issuer differs from the trusted issuer.

Expired

The pass has reached its expiry.

NotYetValid

The pass starts in the future.

UnpublishedKey(String)

No published verification key has this id.

Signature(SignatureError)

Strict signature verification failed.

Encoding(DecodeError)

A compact token segment was not canonical base64url.

Json(Error)

A signed claim or published key could not be read.

RightsOutsideAudience

A pass contains another application’s rights.

Truncated(String)

The issuer omitted rights for this application.

Invalid(&'static str)

A boundary value violates the published contract.

Transport(Box<dyn Error + Send + Sync>)

A live request failed before a contract answer was received. The transport’s own error, typed by no HTTP stack, so the variant stands whether or not the http feature is on.

CannotAsk(&'static str)

A live response is outside the permission contract.

Url(ParseError)

A supplied endpoint is malformed.

Binding

A pass’s grant binding is absent, unsupported or not the pass’s (DIRECTORY-089 R2), by its stable name.

Fields

name: &'static str

The binding’s stable refusal name.

reason: &'static str

Its words.

TokenRefused

A named issuer refusal of the exchange or refresh.

Fields

name: String

The issuer’s stable refusal name.

reason: String

The issuer’s refusal words.

Implementations

impl Error

pub fn name(&self) -> &str

The stable machine name, without keys, credentials or response bodies.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<DecodeError> for Error

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
