Functions

func BackwardTransformIfSystem

func BackwardTransformIfSystem(key string) string

func GetContextFromRequest

func GetContextFromRequest(c *fasthttp.RequestCtx) context.Context

GetContextFromRequest returns main context from fasthttp request context.

func GetReqLog

func GetReqLog(ctx context.Context) *zap.Logger

GetReqLog returns log if set. If zap.Logger isn't set returns nil.

func GetReqLogOrDefault

func GetReqLogOrDefault(ctx context.Context, defaultLog *zap.Logger) *zap.Logger

GetReqLogOrDefault returns log from context, if it exists. If the log is missing from the context, the default logger is returned.

func PrepareExpirationHeader

func PrepareExpirationHeader(ctx context.Context, epochFetcher EpochInfoFetcher, headers map[string]string, now time.Time) error

func SetContextToRequest

func SetContextToRequest(ctx context.Context, c *fasthttp.RequestCtx)

SetContextToRequest adds new context to fasthttp request.

func SetHTTPTraceInfo

func SetHTTPTraceInfo(ctx context.Context, span trace.Span, req *fasthttp.RequestCtx)

SetHTTPTraceInfo saves trace headers to response.

func SetReqLog

func SetReqLog(ctx context.Context, log *zap.Logger) context.Context

SetReqLog sets child zap.Logger in the context.

func StartHTTPServerSpan

func StartHTTPServerSpan(ctx context.Context, req *fasthttp.RequestCtx, operationName string, opts ...trace.SpanStartOption) (context.Context, trace.Span)

StartHTTPServerSpan starts root HTTP server span.

func TransformIfSystem

func TransformIfSystem(key []byte) []byte

Types
