Errors produced by Ibct::issue and Ibct::verify.

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.

InvalidSignature

The HMAC-SHA256 signature does not match the token’s fields. Indicates tampering or use of a wrong key.

Expired

The token’s expires_at is in the past beyond the clock-skew grace window.

Fields

expires_at: u64

now: u64

EndpointMismatch

The token is bound to a different endpoint than the one being verified.

Fields

expected: String

got: String

TaskMismatch

The token is bound to a different task ID than the one being verified.

Fields

expected: String

got: String

UnknownKeyId

The token’s key_id is not present in the verifier’s key set. Either the key was rotated out or the token was issued by a different party.

Fields

key_id: String

FeatureDisabled

This crate was compiled without the ibct feature flag.

Base64(DecodeError)

The base64 token string could not be decoded.

Json(Error)

The decoded bytes are not valid JSON for an Ibct struct.

Trait Implementations

impl Debug for IbctError

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

Formats the value using the given formatter.

impl Display for IbctError

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

Formats the value using the given formatter.

impl Error for IbctError

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 IbctError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for IbctError

fn from(source: Error) -> Self

Converts to this type from the input type.
