Fields

schema: String

kernel: String

entry: String

plan_cc: String

device_name: String

device_cc: String

driver_version: String

candidates: Vec<CandidateResult>

total_gpu_seconds: f64

strategy: Option<String>

Strategy that produced the visiting order (exhaustive | random:<seed>).

budget_exhausted: bool

True when the sweep stopped because the wall budget ran out.

Implementations

impl Results

pub fn load(path: &Path) -> Result<Option<Self>, String>

Read results.v1 from a run directory.

Ok(None) means one thing only: the file is not there, so the measurement box has not run yet. Everything else is an error.

This used to be read_to_string(path).ok()? then from_str().ok(), so a truncated file, an empty one, null, [], a results.v2 from a newer runner and a directory named results.json all collapsed into that same None — and report rendered “nothing measured yet”, exit 0, nothing on stderr, with a JSON report that validated. The run directory is the hand-off between two machines, and the two conditions call for opposite actions: wait, or go and look. Nothing told them apart.

verdicts.v1 two lines away in the report builder already checked its schema tag by name; this is the same check, so a future results.v2 is refused by name rather than read as nothing.

Errors

Any I/O error that is not NotFound, any parse failure, and any document whose schema is not results.v1 — each naming the path.

pub fn checkpoint(&self, path: &Path) -> Result<(), String>

Atomic checkpoint: write to a temp file, then rename.

Trait Implementations
