Get single data of a off-chain data feed for @chainlink/solana-sdk

How does a one the latest round data similar to EVM chain get latest data
If non is available, show an example for how to get this from data.onRound listener

You could wrap the onRound listener into a promise, we do that in the tests:

chainlink-solana/ts/src/index.test.ts

Lines 94 to 101 in 805ddc7

    
           let resolve; 
        
           let promise = new Promise<Round>((r) => (resolve = r)); 
        
           let num; 
        
           num = cl.onRound(CHAINLINK_STORE_PROGRAM_ID, (round) => { 
        
             resolve(round); 
        
             cl.removeListener(num); 
        
           }); 
        
           let got = await promise;

closing stale issue

	let resolve;
	let promise = new Promise<Round>((r) => (resolve = r));
	let num;
	num = cl.onRound(CHAINLINK_STORE_PROGRAM_ID, (round) => {
	resolve(round);
	cl.removeListener(num);
	});
	let got = await promise;
