# nemo-relay-worker-proto

> Versioned gRPC protocol for NeMo Relay out-of-process worker plugins.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

Versioned gRPC protocol for NeMo Relay out-of-process worker plugins.

The protobuf schema owns transport control flow and the tool-result wrapper structure. Open application payloads remain lossless JSON values, while other Relay data transfer objects are carried in JSON envelopes.

## Modules

* [v1](/reference/api/rust-library-reference/nemo-relay-worker-proto/v1): Generated protobuf and gRPC service definitions.

## Constants

* [DIAGNOSTIC_NOT_CONSUMED_METADATA](/reference/api/rust-library-reference/nemo-relay-worker-proto/constant-diagnostic-not-consumed-metadata): Metadata set to `1` on a diagnostic admission rejection before execution. This certifies only that attempt; an earlier lost reply can still be uncertain.
* [DOWNSTREAM_CONTINUATION_METADATA](/reference/api/rust-library-reference/nemo-relay-worker-proto/constant-downstream-continuation-metadata): Continuation provenance for an error returned as gRPC status metadata. Used for stream-opening failures, where no `WorkerError` envelope is returned.
* [WORKER_PROTOCOL_GRPC_V1](/reference/api/rust-library-reference/nemo-relay-worker-proto/constant-worker-protocol-grpc-v1): Stable worker protocol identifier accepted by `compat.worker_protocol`.

## Functions

* [decode_json_envelope](/reference/api/rust-library-reference/nemo-relay-worker-proto/fn-decode-json-envelope): Decodes a JSON envelope into the requested DTO type.
* [decode_json_value](/reference/api/rust-library-reference/nemo-relay-worker-proto/fn-decode-json-value): Decodes a lossless protocol JSON value into the requested type.
* [json_envelope](/reference/api/rust-library-reference/nemo-relay-worker-proto/fn-json-envelope): Creates a JSON envelope from a serializable DTO.
* [json_value](/reference/api/rust-library-reference/nemo-relay-worker-proto/fn-json-value): Creates a lossless protocol JSON value from a serializable value.
