Enum ParseError

#[non_exhaustive]
pub enum ParseError {
    InvalidTokenStructure,
    InvalidBase64Encoding,
    MalformedHeader(Error),
    UnsupportedContentType(String),
    ClaimsTooLarge,
    SignatureTooLarge,
    SignedDataTooLarge,
}

Errors that may occur during token parsing.

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.

InvalidTokenStructure

Token has invalid structure.

Valid tokens must consist of 3 base64url-encoded parts (header, claims, and signature) separated by periods.

InvalidBase64Encoding

Cannot decode base64.

MalformedHeader(Error)

Token header cannot be parsed.

UnsupportedContentType(String)

Content type mentioned in the token header is not supported.

Supported content types are JSON (used by default) and CBOR (only if the ciborium crate feature is enabled, which it is by default).

ClaimsTooLarge

Payload is too large.

SignatureTooLarge

Signature too large.

SignedDataTooLarge

Signed data too large.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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.
