Crate pallet_validator_set_announcer 

Validator Set Announcer pallet.

Applies the validator set of each era locally and hands it to Config::Sender for the other system chains. Meant for the chain that runs pallet-staking-async, typically Asset Hub.

Overview

The runtime calls Pallet::announce when a new era becomes active. It stores the set in the local pallet-validator-collators. If the receiver accepts it, the pallet hands the set to the sender once for every destination in Config::Destinations and deposits Event::AnnouncementSent or Event::AnnouncementFailed for each. A set the receiver rejects is reported with Event::AnnouncementRejected and not sent. Acceptance by the sender means the message was queued for delivery. Execution on the destination is not acknowledged.

The pallet holds no storage. A failed send is not retried: every error an HRMP enqueue can return persists for the rest of the era, and the next era’s announcement carries the full set again.
