Struct PreparedTune 

pub struct PreparedTune { /* private fields */ }

Everything prepare resolves before a tune’s long-running polling phase can start: the already-validated ValidatedTuneRequest, the resolved template and derived tags, a connected driver, the built [LoopConfig], the run’s start time, and the response level (if any) to write back at the end – plus the tune_runs row’s assigned id.

The first phase (template lookup, tag derivation, driver connect, and the tune_runs insert that assigns PreparedTune::run_id) is fast enough to await in an HTTP request handler, which can then spawn drive and return the assigned id before the tune ends.

Every field but run_id is private: a caller that isn’t this module has no legitimate reason to inspect a template/tags/driver/config mid-flight, only to hand the whole prepared bundle to drive unchanged.

Implementations

impl PreparedTune

pub fn run_id(&self) -> i64

The tune_runs row id assigned to this run – returned to an HTTP caller immediately (before the run has necessarily finished, or even started polling) so it can be used to poll GET /api/runs/{id} or issue POST /api/runs/{id}/cancel.
