Struct ReactiveDescribeHandle 

pub struct ReactiveDescribeHandle { /* private fields */ }

Id-bearing handle for a reactive describe subscription.

D246 rule 3: Core-free (Send), no RAII Drop — teardown is the owner-invoked synchronous Self::detach. This eliminates the “unsubscribe in Drop” deadlock class. The embedder’s Teardown is the owner-invoked Self::detach(core) — REQUIRED. The ns-sink is also collected by graph.destroy(core); the Core topology sub is opened via raw core.subscribe_topology and is NOT OwnedCore-tracked, so only detach(core) collects it.

Implementations

impl ReactiveDescribeHandle

pub fn detach(&self, core: &Core)

Owner-invoked, synchronous detach (D246 rule 3). Topology sub first (so a topo fire mid-detach can’t re-snapshot through a half-removed namespace sink), then the namespace sink.
