Enum GeneratorSpec 

pub enum GeneratorSpec {
    Watdiv {
        scale: u32,
        stress: WatdivStressSpec,
    },
    WatdivBasic {
        scale: u32,
    },

        ontology: String,
        queries: Option<Vec<String>>,
    },
}

A declarative generator spec. Tagged on the kind field (kind: watdiv or kind: lubm).

Variants

Watdiv

Drives the WatDiv pipeline (kermit_rdf::pipeline::run_pipeline).

Fields

scale: u32

Scale factor passed to watdiv -d (>= 1).

stress: WatdivStressSpec

Stress-template parameters. Defaults to the same values as the bench gen watdiv CLI defaults.

WatdivBasic

Drives the WatDiv Basic Testing workload — the 20 canonical L/S/F/C query templates (kermit_rdf::pipeline::run_basic_pipeline). Carries no stress parameters: the templates are fixed.

Fields

scale: u32

Scale factor passed to watdiv -d (>= 1).

Lubm

Drives the LUBM pipeline (kermit_rdf::lubm::pipeline::run_lubm_pipeline).

Fields

scale: u32

Universities to generate (-u); must be >= 1.

seed: u32

RNG seed (-s). Default 0.

threads: u32

Worker thread count (-t). Default 1 for reproducibility.

start_index: u32

Starting university index (-i). Default 0.

ontology: String

Ontology IRI (--ontology). Default DEFAULT_LUBM_ONTOLOGY.

queries: Option<Vec<String>>

Optional subset of the 14 LUBM queries to run, by stem (q1 … q14). None or omitted = all 14.

Implementations

impl GeneratorSpec

pub fn spec_hash(&self) -> String

Computes the canonical SHA-256 hash of this spec, used by the materialization layer to detect parameter drift against a cached meta.json. Hashes the YAML serialization of the spec; field ordering is fixed by the struct/enum definition so the output is deterministic across runs and platforms (no HashMap fields).

Panics

Panics if serde_yaml::to_string fails for Self. The serializer is total over all GeneratorSpec values.

Trait Implementations

impl Clone for GeneratorSpec

fn clone(&self) -> GeneratorSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeneratorSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeneratorSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for GeneratorSpec

impl PartialEq for GeneratorSpec

fn eq(&self, other: &GeneratorSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GeneratorSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
