Struct StateUpdate 

pub struct StateUpdate {
    pub published: u64,
    pub replaced: u64,
    pub payload: Arc<Bytes>,
}

The latest frame published to one state key, and how many frames the key has published in total.

A state bus keeps only the latest frame, so frames published faster than a subscriber reads them are overwritten. The count lets the subscriber tell: if it moved by more than one since its last read, frames were skipped.

Fields

published: u64

replaced: u64

published as of the latest frame that replaced the entity instead of patching it: an upsert or a delete. If it is past a subscriber’s last read, a client’s copy may hold fields the entity no longer has, which no patch removes. Zero until one is published.

payload: Arc<Bytes>
