Absolute module path via crate_name::

help
1

hi,
i have a module m with 2 sub-modules s1 and s2 with paths

    crate::m::s1
    crate::m::s2

module s2 contains a variable named x
my crate is named kop
inside module s1 i can do

    crate::m::s2::x // use x contained in module s2 from module s1

however instead i would like to use the crate name "kop" to write

    kop::m::s2::x

can this be done?
thx

Inside of s1, you can write:

use crate as kop;

and then you can refer to kop::m::s2::x.

many thx!

can this be done on a global level? so that i don't have to write "use crate as kop;" in every submodule?

Yes, you can use extern crate self as name; in your lib.rs to add name to the prelude of names available anywhere in your crate.
