Enum TokenError 

pub enum TokenError {
    CacheExpired,
    EmptyAccessToken,
    FetchFailed(Error),
    FileReadError(String),
    InvalidToken(Error),
    MissingId,
    UnknownAlgorithm,
    UnknownKeyId(String),
}

Errors that can occur when fetching or forwarding a token.

Variants

CacheExpired

The keys are not yet populated or TTL elapsed.

EmptyAccessToken

The token endpoint responded successfully but the access_token field was empty.

FetchFailed(Error)

FileReadError(String)

A platform-injected token file could not be read. Carries the file path and OS error message.

InvalidToken(Error)

The JWT signature or standard claims (expiry, issuer) are invalid.

MissingId

A header is missing its kid field.

UnknownAlgorithm

The JWT header names an algorithm this library does not support.

UnknownKeyId(String)

The JWT header names a kid that is not present in the loaded key set.

Trait Implementations

impl Debug for TokenError

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

Formats the value using the given formatter.

impl Display for TokenError

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

Formats the value using the given formatter.

impl Error for TokenError

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<Error> for TokenError

fn from(e: Error) -> TokenError

Converts to this type from the input type.

impl From<TokenError> for AuthError

fn from(value: TokenError) -> AuthError

Converts to this type from the input type.
