Read an aggregator result on-chain

use switchboard::aggregator;
use switchboard::math;

// store latest value
struct AggregatorInfo has copy, drop, store, key {
  aggregator_addr: address,
  latest_result: u128,
  latest_result_scaling_factor: u8,
  latest_result_neg: bool,
}

// get latest value
public fun save_latest_value(aggregator_addr: address) {
  // get latest value
  let latest_value = aggregator::latest_value(aggregator_addr);
  let (value, scaling_factor, neg) = math::unpack(latest_value);
  move_to(account, AggregatorInfo {
      aggregator_addr: aggregator_addr,
      latest_result: value,
      latest_result_scaling_factor: scaling_factor,
      latest_result_neg: neg,
  });
}

// some testing that uses aggregator test utility functions
#[test(account = @0x1)]
public entry fun test_aggregator(account: &signer) {

  // creates test aggregator with data
  aggregator::new_test(account, 100, 0, false);

  // print out value
  std::debug::print(&aggregator::latest_value(signer::address_of(account)));
