Function ensureResetMaskInMetadata

ensureResetMaskInMetadata(msg: any, metadata?: Metadata): Metadata
Adds a reset-mask header for an update message when one is not already set.

The function uses the supplied Metadata object, or creates one when metadata is absent. It does not replace an existing x-resetmask value. It omits the header when msg is null or undefined.

The SDK normally calls this function for update requests. Call it directly only when you build gRPC metadata outside the standard request API.
Parameters
- msg: any
- Optionalmetadata: Metadata
Returns Metadata
The supplied metadata object, or a new metadata object.
Example
```
import { Metadata } from '@grpc/grpc-js';
import {
  ensureResetMaskInMetadata,
  RESET_MASK_HEADER,
} from '@nebius/js-sdk/runtime/resetmask';

const metadata = ensureResetMaskInMetadata(
  { displayName: '', enabled: false },
  new Metadata(),
);
metadata.get(RESET_MASK_HEADER); // ["displayName,enabled"]
```
Throws
ErrRecursionTooDeep if the message is too deeply nested.
