Shared serializable data model types for NeMo Relay.

This crate contains DTOs and wire-compatible type definitions used by the runtime and native plugin SDK. It intentionally does not contain runtime registries, dynamic loading, codecs, exporters, or process-global state.

## Modules

* [api](/reference/api/rust-library-reference/nemo-relay-types/api): Public runtime API data types. Shared API data types.
* [codec](/reference/api/rust-library-reference/nemo-relay-types/codec): Normalized LLM request and response data types. Shared normalized LLM request and response data types.
* [plugin](/reference/api/rust-library-reference/nemo-relay-types/plugin): Plugin configuration diagnostic data types. Shared plugin diagnostic data types.

## Type Aliases

* [Json](/reference/api/rust-library-reference/nemo-relay-types/type-json): Type alias for [`serde_json::Value`](https://docs.rs/serde_json/1.0.149/serde_json/value/enum.Value.html), used as the universal JSON representation throughout NeMo Relay APIs.
