Shall there be a cfg feature that removes all the overhead and features?

[vi]

Shall there be some compile-time knob that renders all async_backtrace::framed annotations no-ops? (and makes backtrace and other functions return dummy values).

Something like log's or tracing's max_level_off / release_max_level_off.

That sounds like a great idea! I'll look into it.

Would be useful.
My current workaround is:

#[cfg_attr(debug_assertions, async_backtrace::framed)]
async fn foo(...) { ... }

and

macro_rules! traced {
    ($e:expr) => {{
        #[cfg(debug_assertions)]
        {
            async_backtrace::location!().frame($e)
        }

        #[cfg(not(debug_assertions))]
        {
            $e
        }
    }};
}

runtime.block_on(traced!(async {
    ....
}));
