Attribute Macro module_unload

#[module_unload]

Helper for unloading a Tcl extension.

This macro will automatically create the appropriate wrapper to validate the interpreter and pass it to the given unload routine. The prototype of the wrapped function should be

type unload_fn = fn(interp: &rtea::Interpreter, flags: TclUnloadFlag) -> Result<rtea::TclStatus, String>;

and the module’s name (as given to [module_init]) should be given as the sole attribute to the macro.
