Mutate Extension (WriteableSession) in Response

[michaelmerrill]

Is there a way I can access axum_sessions::extractors::WritableSession from into_response? The following is what I've tried, but it doesn't seem to update the session.

impl IntoResponse for LoginError {
    fn into_response(self) -> Response {
        let mut response = Redirect::to("/login").into_response();
        response
            .extensions_mut()
            .get_mut::<WritableSession>()
            .map(|session| session.insert("_login_error", self.to_string()));
        response
    }
}

The response you create with Redirect::to("/login").into_response() is a completely new response that doesn't know anything about the corresponding request, so it wont have any extensions.

Shoulds like you're looking for a middleware https://docs.rs/axum/latest/axum/middleware/fn.from_fn.html
