Module broadcast

Expand description

Process-wide broadcast channel for the canonical log stream.

Functions§

clear_broadcast_hook: Remove the broadcast sender (tests, orderly shutdown).
current_broadcast_hook: Read the current broadcast sender, if any.
set_broadcast_hook: Install a process-wide broadcast sender. Calling again replaces the previous one (the old sender will be dropped — its Receivers will see RecvError::Closed on their next read).
subscribe: Subscribe to the broadcast stream. Returns None when no sender has been installed yet (e.g. when running tests that never wired the gateway). The receiver yields every event emitted via crate::record_event after the subscribe call.
