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::EngineRow;

pub use data::EuModelRow;
