Enum Error

pub enum Error {
    ChallengeParse(String),

    SignedUrlKeyTooShort {
        kid: String,

Errors produced by challenge parsing / response computation.

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.

ChallengeParse(String)

The WWW-Authenticate challenge value could not be parsed (RFC 7235 / RFC 2326 §14 for a Basic or Digest challenge).

ResponseCompute(String)

The Authorization response value could not be computed from the parsed challenge and credentials (e.g. an unsupported Digest algorithm/qop).

SignedUrlKeyTooShort

crate::SignedUrlKeySet::new rejected a key whose secret is shorter than the required minimum (issue #747) — a setup-time error, never returned from request verification. The kid is included since this is a config-diagnostic error, not an attacker-facing one.

Fields

kid: String

The offending key’s id.

min: usize

The required minimum secret length in bytes.

actual: usize

The offending secret’s actual length in bytes.

UnknownSignedUrlKeyId(String)

crate::SignedUrlKeySet::sign was asked to mint a token for a kid the keyset has no secret for. Only reachable from the signing helper (used by tests/operators minting URLs) — never from crate::Verifier::verify, which folds every signed-URL rejection reason into the same crate::AuthResult::Unauthorized (see that module’s docs).

InvalidBearerToken

A Bearer token cannot be carried in an Authorization header value — it contains a byte outside visible ASCII (control character, CR/LF, or non-ASCII) — so no header was produced rather than a corrupt or injectable one.

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, __formatter: &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>)
