Types

type AdaptedBidder

type AdaptedBidder interface {
	// contains filtered or unexported methods
}

AdaptedBidder defines the contract needed to participate in an Auction within an Exchange.

This interface exists to help segregate core auction logic.

Any logic which can be done _within a single Seat_ goes inside one of these. Any logic which _requires responses from all Seats_ goes inside the Exchange.

This interface differs from adapters.Bidder to help minimize code duplication across the adapters.Bidder implementations.

func AdaptBidder

func AdaptBidder(bidder adapters.Bidder, client *http.Client, cfg *config.Configuration, me metrics.MetricsEngine, name openrtb_ext.BidderName, debugInfo *config.DebugInfo, endpointCompression string) AdaptedBidder

AdaptBidder converts an adapters.Bidder into an exchange.AdaptedBidder.

The name refers to the "Adapter" architecture pattern, and should not be confused with a Prebid "Adapter" (which is being phased out and replaced by Bidder for OpenRTB auctions)

type AuctionRequest

type AuctionRequest struct {
	BidRequestWrapper          *openrtb_ext.RequestWrapper
	ResolvedBidRequest         json.RawMessage

	ImpExtInfoMap              map[string]ImpExtInfo
	TCF2Config                 gdpr.TCF2ConfigReader
	Activities                 privacy.ActivityControl

	// LegacyLabels is included here for temporary compatibility with cleanOpenRTBRequests
	// in HoldAuction until we get to factoring it away. Do not use for anything new.
	LegacyLabels   metrics.Labels
	FirstPartyData map[openrtb_ext.BidderName]*firstpartydata.ResolvedFirstPartyData
	// map of imp id to stored response
	StoredAuctionResponses stored_responses.ImpsWithBidResponses
	// map of imp id to bidder to stored response
	StoredBidResponses      stored_responses.ImpBidderStoredResp
	BidderImpReplaceImpID   stored_responses.BidderImpReplaceImpID
	PubID                   string
	HookExecutor            hookexecution.StageExecutor
	QueryParams             url.Values
	BidderResponseStartTime time.Time
	TmaxAdjustments         *TmaxAdjustmentsPreprocessed
}

AuctionRequest holds the bid request for the auction and all other information needed to process that request

type AuctionResponse

type AuctionResponse struct {
	*openrtb2.BidResponse
	ExtBidResponse *openrtb_ext.ExtBidResponse
}

AuctionResponse contains OpenRTB Bid Response object and its extension (un-marshalled) object

func (*AuctionResponse) GetSeatNonBid

func (ar *AuctionResponse) GetSeatNonBid() []openrtb_ext.SeatNonBid

GetSeatNonBid returns array of seat non-bid if present. nil otherwise

type BidIDGenerator

type BidIDGenerator interface {
	New() (string, error)
	Enabled() bool
}

type BidderRequest

type BidderRequest struct {
	BidRequest            *openrtb2.BidRequest
	BidderName            openrtb_ext.BidderName
	BidderCoreName        openrtb_ext.BidderName
	BidderLabels          metrics.AdapterLabels
	BidderStoredResponses map[string]json.RawMessage
	IsRequestAlias        bool
	ImpReplaceImpId       map[string]bool
}

BidderRequest holds the bidder specific request and all other information needed to process that bidder request.

type DebugData

type DebugData struct {
	Request  string
	Headers  string

type Exchange

type Exchange interface {
	// HoldAuction executes an OpenRTB v2.5 Auction.
	HoldAuction(ctx context.Context, r *AuctionRequest, debugLog *DebugLog) (*AuctionResponse, error)
}

Exchange runs Auctions. Implementations must be threadsafe, and will be shared across many goroutines.

func NewExchange

func NewExchange(adapters map[openrtb_ext.BidderName]AdaptedBidder, cache prebid_cache_client.Client, cfg *config.Configuration, syncersByBidder map[string]usersync.Syncer, metricsEngine metrics.MetricsEngine, infos config.BidderInfos, gdprPermsBuilder gdpr.PermissionsBuilder, currencyConverter *currency.RateConverter, categoriesFetcher stored_requests.CategoryFetcher, adsCertSigner adscert.Signer, macroReplacer macros.Replacer, priceFloorFetcher floors.FloorFetcher) Exchange
