# codetics-ocpp16

Every OCPP 1.6 (OCPP-J) message as plain Rust types, following the specification's type names and the
1.6-J errata 2025-04 (both `Celcius` and `Celsius` accepted, `StopTransaction.reason` optional):

- `serde` mappings matching the message definitions (required fields, enumerations, no unknown fields);
- `Validate` implementations for length, range, cardinality and `multipleOf` constraints, with violations mapped
  to the right OCPP-J error code;
- `Action` with message direction, and typed dispatch: `StationCall` (Charge Point → Central System)
  and `CsmsCall` (Central System → Charge Point).

```rust
use codetics_ocpp16::{DecodeError, StationCall};

let call = StationCall::decode("BootNotification", r#"{"chargePointVendor":"VendorX","chargePointModel":"X1"}"#).unwrap();
let StationCall::BootNotification(boot) = call else { unreachable!() };
assert_eq!(boot.charge_point_vendor, "VendorX");

// Reset is sent by the Central System, not by a Charge Point.
assert!(matches!(StationCall::decode("Reset", r#"{"type":"Hard"}"#), Err(DecodeError::WrongDirection(_))));
```
