Attribute Macro perseus::browser_only_fn

#[browser_only_fn]

A convenience macro that makes sure the given function is only defined on the browser-side, creating an empty function on the engine-side. Perseus implicitly expects your browser-side state modification functions to be defined in this way (though you certainly don’t have to use this macro).

Note that this will convert async functions to non-async functions on the engine-side (your function will be left alone on the browser-side).
