Trait Implementations§

Source§

impl DatasetAdapter for TpcDs

Source§

fn name(&self) -> &'static str

Display name (for reports + figure captions).
Source§

fn load(&self, path: &Path) -> Result<ResidualStream>

Load a real subset from path. Errors if the file/directory is missing, malformed, or empty.
Source§

fn exemplar(&self, seed: u64) -> ResidualStream

Generate a deterministic synthetic exemplar with the dataset’s statistical shape. seed makes the run reproducible. The returned stream’s source will be "{name}-exemplar-seed{seed}" so that no downstream report mislabels it as real data.
