Trait Implementations

impl SubmitPolicy for ChoirPolicy

fn check(&mut self, sub: &Submission) -> Result<(), String>

Accepts or rejects a submission. Runs on the writer thread, so a stateful policy (e.g. one holding a cached materialized view) sees submissions in their final total order.

fn accepted(&mut self, entry: &OpEntry, _hash: &ContentHash)

Observes an entry that was just appended (for cached-state policies to fold). Default: ignore.

fn subject(&self) -> (Option<String>, Option<String>)

What the last SubmitPolicy::check identified about its submission: (actor_id, op_type), for the journal.
