Crate vin_decode 

Auto-updating VIN decoder backed by the NHTSA vPIC database.

This crate ships pre-built FST/rkyv lookup maps that get refreshed monthly from the official NHTSA vPIC dump via CI. End users get fresh decoder data without ever touching the network at runtime.

Example

use vin_decode::Decoder;

let dec = Decoder::new()?;
let v = dec.decode("1HGCM82633A004352")?;
assert_eq!(v.make.as_deref(), Some("Honda"));

Re-exports

pub use data::BodyRow;

pub use data::EngineRow;

pub use data::EuModelRow;

Modules

data

Internal rkyv archive types for the lookup tables.

Structs

Catalog

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

Decoder

VIN decoder backed by mmap’d FST/rkyv lookup maps.

Vehicle

Fully decoded vehicle attributes derived from a single VIN.

Vin

A validated 17-character VIN.

Enums

BodyType

Vehicle bodywork type, per the EU type-approval standard — the two-letter codes from Commission Regulation (EU) 678/2011 (consolidated into the framework Reg (EU) 2018/858), the same codes printed on the Certificate of Conformity and recorded by EU national vehicle registers.

DriveType

Drive layout, normalised from the free-text drive strings in the engine catalog ("Front Wheel Drive", "All Wheel Drive", …).

Error

Errors produced during VIN parsing and decoding.

FuelType

Fuel-type enumeration the decoder normalizes vPIC strings into.

Transmission

Transmission type, normalised from the free-text gearbox strings in the engine catalog ("6-Speed Manual", "7-Speed Dual Clutch", "CVT", …). Gear count is separate — see crate::EngineRow::gearbox_speeds.

Functions

country_from_code

Map a 2-char country code (VIN positions 1-2) to a country name.

region_from_code

Map a VIN’s first character (region code) to its ISO 3779 region name.
