+this gave some issues when trying to import the crate (something with the macro's).
+I couldn't find the fix for this in the documentation so i decided in the end to go back to the ugly but native solution
+
+example of the errors:
+
+```
+error[E0432]: unresolved import `phf::phf_map`
+ --> src\main.rs:5:5
+  |
+5 | use phf::phf_map;
+  |     ^^^^^^^^^^^^ no `phf_map` in the root
+```
+

+```
+error: cannot determine resolution for the macro `phf_map`

+  = note: import resolution is stuck, try simplifying macro imports
