Reading Feeds

Read an aggregator result on-chain

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

// store latest value
struct AggregatorInfo has store, key {
  id: UID,
  aggregator_addr: address,
  latest_result: u128,
  latest_result_scaling_factor: u8,
  latest_timestamp: u64,
}

// get latest value
public entry fun save_aggregator_info(
  feed: &Aggregator,
  ctx: &mut TxContext
) {
  let (latest_result, latest_timestamp) = aggregator::latest_value(feed);

  // get latest value
  let (value, scaling_factor, _neg) = math::unpack(latest_result);
  transfer::transfer(
      AggregatorInfo {
          id: object::new(ctx),
          latest_result: value,
          latest_result_scaling_factor: scaling_factor,
          aggregator_addr: aggregator::aggregator_address(feed),
          latest_timestamp,
