ah, i was considering suggesting using identitylayer to avoid it, but this is obviously better :-)
EDIT: oh, that was for the optional auth branch.

Like this?

let inner = ServiceBuilder::new()
    .layer(common)
    .layer(if let Authentication::RefreshableToken(refreshable) = auth {
        AuthLayer::new(refreshable)
    } else {
        Identity::new()
    })
    .layer(tower::layer::layer_fn(LogRequest::new))
    .service(client);
Ok(Self::new(inner))

This won't compile because if and else have different types.

Maybe there's a better way, but I think it's fine for now if not.

yeah, that's what i was thinking, but if it doesn't work it's not a problem.
makes sense that it doesn't, quite different layer requirements.
