Functions

func AssertEqualModulesData 

func AssertEqualModulesData(t *testing.T, expectedData, actualData json.RawMessage)

AssertEqualModulesData is the test helper function which asserts that expected modules data fully corresponds the actual modules data. Dynamic data for execution time is calculated from actual modules data.

func EnrichExtBidResponse 

func EnrichExtBidResponse(
	ext json.RawMessage,
	stageOutcomes []StageOutcome,
	bidRequest *openrtb2.BidRequest,
	account *config.Account,
) (json.RawMessage, []error, error)

EnrichExtBidResponse adds debug and trace information returned from executing hooks to the ext argument. In response the outcome is visible under the key response.ext.prebid.modules.

Debug information is added only if the debug mode is enabled by request and allowed by account (if provided). The details of the trace output depends on the value in the bidRequest.ext.prebid.trace field. Warnings returned if bidRequest contains unexpected types for debug fields controlling debug output.

func GetModulesJSON 

func GetModulesJSON(
	stageOutcomes []StageOutcome,
	bidRequest *openrtb2.BidRequest,
	account *config.Account,
) (json.RawMessage, []error, error)

GetModulesJSON returns debug and trace information produced from executing hooks. Debug information is returned only if the debug mode is enabled by request and allowed by account (if provided). The details of the trace output depends on the value in the bidRequest.ext.prebid.trace field. Warnings returned if bidRequest contains unexpected types for debug fields controlling debug output.

func NewHookExecutor 

func NewHookExecutor(builder hooks.ExecutionPlanBuilder, endpoint string, me metrics.MetricsEngine) *hookExecutor
