Trait A2uiReplayBackbone 

pub trait A2uiReplayBackbone: Send + Sync {
    // Required methods
    fn publish(&self, run_id: &str, op: StatePatchOp);
    fn replay(&self, run_id: &str) -> Vec<StatePatchOp>;
}

A durable-replay backbone for A2UI state patches, keyed by run_id. Distinct from RunManager’s live broadcast: this trait’s job is specifically “can a client that joins after some patches were already published still receive them,” which a tokio::sync::broadcast channel cannot do once its buffer has advanced past a slow/late subscriber.

Required Methods

fn publish(&self, run_id: &str, op: StatePatchOp)

Publishes a patch for run_id, retaining it for later replay.

fn replay(&self, run_id: &str) -> Vec<StatePatchOp>

Returns every patch published for run_id so far, in publish order. A late-joining client calls this once on connect (its “reattach”), then switches to the live broadcast for anything published after.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
