@@ -74,9 +74,9 @@ there is another crate in m-c called moz
the same folder to store its rust dependencies. If one of the libraries that is
required by both mozjs_sys and webrender is updated without updating the other
project's Cargo.lock file, that results in build bustage.
This means that any time you do this sort of manual update of packages, you need
to make sure that mozjs_sys also has its Cargo.lock file updated if needed, hence
the need to run the cargo update command in js/src as well. Hopefully this will
be resolved soon.
