Required Methods§

Source

fn accept_seq(&self) -> u64

Source

fn authority(&self, action: Self::Action) -> Self::AuthorityAction

Converts a client action into an authority action.

This method must not rely on observing effects from recently returned authority actions. Leaders may enqueue authority actions before the local hot-read snapshot has applied earlier actions, and forwarded actions may be authorized concurrently. Use this for stateless wrapping or validation of client context; state-dependent sequencing should happen in update.
