Function isBidPartiallyFilled

Determines if a bid is partially filled at the clearing price.

A bid is considered partially filled when:

• The bid is at the clearing price (bid number matches clearing price bid number)
• The bid requests more tokens than are available at the clearing price

This occurs when the auction's token supply is exhausted at the clearing price, causing the last bid at that price to receive only a portion of their requested tokens.

Returns

True if the bid is partially filled, false if fully filled or not at clearing price

Example

const auction = await fetchAuctionBucketV1(umi, auctionPda);
const bid = await fetchAuctionBidV1(umi, bidPda);
const isPartial = isBidPartiallyFilled(auction, bid); // true (partial fill at clearing price)
