Module peer_selector 

bb::PeerSelector — Contract trait for peer-selection protocols.

Every method takes ctx: &mut RuntimeResourceRef<'_> as the first parameter after &mut self (the uniform shape shared by every Contract trait) plus a CompletionHandle AND returns ContractResponse. See crate::contracts::index for the sync (Now) vs async (Later) semantics.

Selector impls read ctx.peers.addresses to walk the local AddressBook, write through it for membership updates from the dispatch_atomic arm (Announce / Forget), and reach the shared Scheduler via ctx.time when they need to plan a delayed probe. Declared dependencies are reached via ctx.dependency::<T>(slot).

Enums

SelectParams

Parameters describing what peer set to select. Different concrete selectors handle the variants they support and return an error variant for the ones they don’t (e.g. GlobalRegistry supports Random + All; DhtView supports NearKey).
