Note: we have the above pattern a lot. For `Schema` we already have a
bunch of `const fn unwrap_<type>_schema()`.
We can now also use `const {}` expressions, so maybe we should have
something like this for `ApiHandler` as well, with all these handler
functions then using something like:

    let handler = const { info.handler.unwrap_async_handler() };
    let result = (handler)(param, info, rpcenv).await?
