Impl Guard for T

pub trait Guard {
    fn check_guard(&self, expected:&Self) -> bool;
}

Where the values for self are extracted from the request based on FromRequestParts<State> for T and the values for expected are given inside the layer on the route.

Router::with(state.clone())
            .route("/", get(ok))
            .layer(
                    GuardService::new(
                        state.clone(),
                        expected.clone()).into_layer()
            );

The argument state passed to GuardService::new() will be the state called inside the FromRequestParts implementation on T

You can also nest using AND/OR logic.

Router::new()
    .route("/", get(ok))
    .layer(
        GuardService::new(state.clone(), expected)
            .and(
                GuardService::new(
                    other_state.clone(), 
                    other_expected
                )
            )
        .into_layer()
);

Will reject StatusCode::UNAUTHORIZED when check_guard returns false.
