Struct Persist 

#[non_exhaustive]
pub struct Persist {
    pub results_dir: PathBuf,
    pub model: String,
    pub backend: String,
    pub cases_dir: String,
}

Where and how to persist a run, attached to a RunMeta via RunMeta::persist_to. When present on the meta passed to a run, the runner writes {slug(model)}_{timestamp_file}.json into results_dir and regenerates results_dir/report.html.

#[non_exhaustive]: build it through the RunMeta builder (persist_to + optional backend_kind / cases_dir), never a struct literal, so new fields stay non-breaking.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

results_dir: PathBuf

Directory the per-run JSON and report.html are written to (created if missing).

model: String

The model / grouping key recorded on the run (RunRecord::model), also used (slugged) in the JSON filename.

backend: String

The backend KIND shown in the report’s Backend column (RunRecord::backend), e.g. "local" / "remote". When empty it falls back to the run’s descriptive backend label (EvalReport::backend).

cases_dir: String

The case directory recorded on the run (RunRecord::cases_dir), shown in the report. May be empty.
