Macro set_supertrait_path 

set_supertrait_path!() { /* proc-macro */ }

Allows you to override the module path where supertrait’s macros will look for necessary re-exports (such as macro_magic).

The default is ::supertrait.

Generally speaking you shouldn’t need to use this directly, but in some scenarios (like in the lib.rs of the main crate, this is necessary).
