Struct Catalog 

pub struct Catalog { /* private fields */ }

Read-only catalog of every make and model present in the lookup data.

Useful for populating dropdowns, validators, or schema-typed enum columns in webapps. Combines the vPIC pattern-derived index (make_models) with the EU/global rip catalog (eu_brand_models, eu_engines) for non-US coverage.

Implementations

impl Catalog

pub fn new() -> Result<Self>

Open the catalog using the default data directory (see crate::Decoder::new).

pub fn open(dir: &Path) -> Result<Self>

Open the catalog against an explicit data directory. EU rip tables are optional — they’re only loaded if the corresponding .fst files exist.

pub fn all_makes(&self) -> Vec<String>

Sorted list of every make name (uppercase, deduped).

pub fn has_make(&self, make: &str) -> bool

Case-insensitive membership check for a make name.

pub fn make_count(&self) -> u64

Total number of distinct makes.

pub fn models_for_make(&self, make: &str) -> Vec<String>

Sorted list of model names known for the given make (case-insensitive lookup).

Merges results from the vPIC pattern-derived index and the EU/global rip catalog, deduped and sorted.

pub fn eu_models_for(&self, brand: &str) -> Vec<EuModelRow>

EU/global rip listing of models for the given brand, with year ranges. Returns an empty vec when the brand is unknown or the EU catalog is not embedded.

pub fn engines_for_brand(&self, brand: &str) -> Vec<EngineRow>

Engine variants known for the given brand. Filter by model in user code, or use Catalog::engines_for.

pub fn engines_for(&self, brand: &str, model: &str) -> Vec<EngineRow>

Engine variants known for (brand, model). Both args are matched case-insensitively against the canonical uppercase keys.

pub fn body_classes() -> &'static [BodyClass]

Static list of every BodyClass variant — useful for typed dropdowns.

pub fn fuel_types() -> &'static [FuelType]

Static list of every FuelType variant — useful for typed dropdowns.
