Enum CallbackError 

pub enum CallbackError {
    StateMismatch,
    Issuer(AuthorizationResponseError),
    Refused {
        error: Arc<str>,
    },
    NoOutcome,
}

Why an authorization callback was refused.

Variants

StateMismatch

The state did not match, or was absent.

RFC 6749 §4.1.2 requires the client validate state. A mismatch means this response is not the answer to the request this client made, which covers a forged redirect, a stale tab, and a callback for a different flow. The two are not distinguished: an attacker learns nothing useful from which, and a client that reported them separately would leak the presence of an outstanding flow.

Issuer(AuthorizationResponseError)

The response named a different authorization server.

Refused

The authorization server refused.

Carries the RFC 6749 §4.1.2.1 error code. This is the server saying no — access_denied, invalid_scope, a user’s “no” at the consent screen — and is deliberately not folded into a generic failure, because a client showing the user “access denied” is doing the right thing.

Fields

error: Arc<str>

The error parameter from the response.

NoOutcome

Neither a code nor an error.

A well-formed response carries exactly one. This is a server sending something this crate cannot interpret, which is not the same as a refusal and not the same as success.
