Module polkadot_node_subsystem_types::messages

Message types for the overseer and subsystems.

These messages are intended to define the protocol by which different subsystems communicate with each other and signals that they receive from an overseer to coordinate their work. This is intended for use with the polkadot-overseer crate.

Subsystems’ APIs are defined separately from their implementation, leading to easier mocking.
