What the engine drives.

Fields

declared: &'a Declared

The declared repo, rendered.

repo: &'a Path

reader: &'a dyn TreeReader

The read half of the master’s host.

host: &'a dyn ApplyHost

The write seam of the master’s host.

deploy: &'a dyn DeployApi

The gateway REST surface (lock, scan, mode, read-back).

gateway: &'a dyn GatewayApi

The gateway log and WebDev surface (verify).

backup: Option<&'a BackupNode<'a>>

The backup node (a read-only handle), when the target has a backup node (the mode_backup preflight).

clock: &'a dyn Clock

The monotonic clock the lock is judged by.

observer: &'a dyn ApplyObserver

Hears each step.
