Implement HolonServiceApi for the ClientHolonService in the client_shared_objects module of the holons_client crate. Each trait method:

[nphias]

• builds the appropriate DanceRequest
• asks the Conductor to call the dance function on the dances zome (encapsulate this in a private helper method)
• processes the DanceResponse and returns results

pub trait HolonServiceApi: Debug {
    /// This function commits the staged holons to the persistent store
    fn commit(&self, context: &dyn HolonsContextBehavior) -> Result<CommitResponse, HolonError>;

    fn delete_holon(&self, holon_id: &HolonId) -> Result<(), HolonError>;

    fn fetch_holon(&self, id: &HolonId) -> Result<Holon, HolonError>;

    fn fetch_related_holons(&self, source_id: &HolonId,  relationship_name: &RelationshipName, ) 
        -> Result<HolonCollection, HolonError>;

    fn fetch_all_populated_relationships(&self, source_id: HolonId, ) 
        -> Result<Rc<RelationshipMap>, HolonError>;
}

Implementation Notes:

• commit method delegates to existing commit_dance
• delete_holon delegates to delete_holon_dance
• fetch_holon delegates to get_holon_by_id_dance
• fetch_related_holons delegates to query_relationships_dance
• fetch_all_populated_relationships doesn't yet have a dance defined. The client implementation can just return a
• HolonError(NotImplemented) for now.
