* introduce the OverseerConnector, use it * introduce is_relay_chain to RelayChainSelection * Update node/service/src/lib.rs Co-authored-by: Andronik Ordian <write@reusable.software> * avoid the deferred setting of `is_relay_chain` in `RelayChainSelection` * positive assertion is not mandated, only the negative one, to avoid a stall * cleanup: overseer residue * spellcheck * fixin * groundwork to obsolete Overseer::new and AllSubsystemsGen proc-macro * Now all malus & tests can be ported to the builder pattern. Obsoletes `Overseer::new`, `AllSubsystemsGen` derive macro, `AllSubsystems`. * spellcheck * adjust tests, minor fixes * remove derive macro AllSubsystemsGen * add forgotten file dummy.rs * remove residue * good news everyone! * spellcheck * address review comments * fixup imports * make it conditional * fixup docs * reduce import * chore: fmt * chore: fmt * chore: spellcheck / nlprules * fixup malus variant-a * fmt * fix * fixins * pfmt * fixins * chore: fmt * remove expanded overseer generation * tracing version * Update node/network/statement-distribution/src/lib.rs Co-authored-by: Robert Habermeier <rphmeier@gmail.com> * use future::ready instead * silence warning * chore: fmt Co-authored-by: Andronik Ordian <write@reusable.software> Co-authored-by: Robert Habermeier <rphmeier@gmail.com>
