The main error type for core JWK/JWKS operations.

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.

Json(Error)

Failed to parse JSON syntax or structure.

Parse(ParseError)

Failed to interpret valid JSON as JWK/JWKS data.

InvalidUrl(ParseError)

Invalid URL input.

InvalidUrlScheme(&'static str)

URL violates a crate-level policy requirement.

InvalidKey(InvalidKeyError)

The JWK is malformed: missing parameters, invalid encoding, or inconsistent fields.

IncompatibleKey(IncompatibleKeyError)

The JWK is well-formed but incompatible with the requested use.

Base64(Error)

Base64 decoding failed.

InvalidInput(&'static str)

Caller provided invalid input to a public API.

Http(Error)

Available on crate feature http only.

HTTP request error.

Fetch(String)

Remote fetch or transport failed outside the reqwest backend.

Cache(String)

Cache operation failed.

Other(String)

Other error (for platform-specific or miscellaneous errors).

UnsupportedForWebCrypto

Available on crate feature web-crypto only.

Key type or curve not supported by WebCrypto.

Fields

reason: &'static str

Why it’s unsupported.

WebCrypto(String)

Available on crate feature web-crypto only.

WebCrypto operation failed.

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, f: &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.
