Struct PeerSelectorSlot 

pub struct PeerSelectorSlot {
    pub class: &'static str,
}

Generic PeerSelector slot placeholder. Bind a concrete PeerSelectorRuntime via Node::with_peer_selector(...). Exposes Sample, CurrentView

class tags every Output<PeerId> this placeholder yields with the class of peer it samples from. The compiler’s infer_peer_classes pass reads that tag to attribute downstream wire.sends to the right destination class - that’s what makes gossip’s self-send case partition correctly (1 class → 1 partition with both send and synthesized recv).

Fields

class: &'static str

Class identifier the compiler stamps onto every produced Output<PeerId> via peer_class metadata. Defaults to bb_ir::peer_class::SELF_CLASS for placeholders constructed via Default - that puts samples on the same class as the registering Node, the natural gossip case.

Implementations

impl PeerSelectorSlot

pub fn of_class(class: &'static str) -> Self

Construct a sampling placeholder bound to the given class. Use PeerSelectorSlot::of_class("gossip_peer") to tag samples as “gossip peers” so a downstream wire.send(payload, neighbor) puts its data output on the same gossip_peer partition.

pub fn sample(&self, g: &mut Graph, n: i64) -> Output

Sample(n) -> peers - Shape 2 (state-dependent sampling).

pub fn current_view(&self, g: &mut Graph) -> Output

CurrentView() -> view - Shape 2 (state read).
