Enum JwsError

pub enum JwsError {
    InvalidFormat {
        parts: usize,
    },
    InvalidBase64Url {
        part: &'static str,

Why a compact JWS could not be decoded or produced.

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.

InvalidFormat

The input is not three base64url parts separated by ..

Fields

parts: usize

The number of .-separated parts found.

InvalidBase64Url

A part is not valid base64url without padding.

Fields

part: &'static str

Which part: header, payload or signature.

InvalidHeader(String)

The protected header is not a JSON object with the expected members.

UnsupportedAlgorithm(String)

The header alg is missing or not a JwsAlgorithm.

UnsupportedCritical(Vec<String>)

The header has a crit member; this crate understands no extensions, so it must reject every one of them (RFC 7515 §4.1.11).

UnencodedPayload

The header sets b64 to false (RFC 7797); only base64url-encoded payloads are supported.

InvalidPayload(String)

The payload cannot be signed as given: a claims set that holds a registered claim under additional next to its field, say.

AlgorithmMismatch

The header alg differs from the algorithm of the signer.

Fields

header: JwsAlgorithm

The alg in the header.

signer: JwsAlgorithm

The algorithm of the signer.

Signer(SignError)

The signer failed.

Trait Implementations

impl Debug for JwsError

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

Formats the value using the given formatter.

impl Display for JwsError

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

Formats the value using the given formatter.

impl Error for JwsError

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.
