The Rust community has been working to reform its governance model; that
work is now being presented as a
draft document describing how that model will work.

This RFC establishes a Leadership Council as the successor of the
core team and the new governance structure through which Rust
Project members collectively confer the authority to ensure
successful operation of the Project. The Leadership Council
delegates much of this authority to teams (which includes subteams,
working groups, etc.) who autonomously make decisions concerning
their purviews. However, the Council retains some decision-making
authority, outlined and delimited by this RFC.
