updateMeta
Merges the provided keys into the call’s custom metadata bag, preserving existing keys not mentioned in _meta. To replace the entire bag instead, use setMeta.
The merged metadata is observed via call.meta$ on all connected peers.
Not yet implemented in v4. This method is on the API surface and will throw when called.
Parameters
_meta
Keys to merge into the metadata bag. Other existing keys are preserved.
Returns
Promise<void> — once implemented, resolves after the server has propagated the merged metadata.
Throws
Throws unconditionally — implementation pending.
