This bug occurred when using Rocket, and with all its crazy macros I'm not quite sure how to minimize my code. 😅 Hopefully what I've shown will still help somewhat.

Code

#[derive(FromForm)]
struct SteamResult<'r> {
    openid: OpenId<'r>
}

#[derive(FromForm)]
struct OpenId<'r> {
    // ...
    identity: &'r str,
    // ...
}
// ...
#[get("/auth?<steam_result..>")]
fn api_auth(steam_result: SteamResult<'static>, cookies: &CookieJar<'_>) -> &'static str {
    steam_result.openid.identity
}
