Types

type Option

type Option func(tracy *TracyGo)

Option is an optional func.

func WithCorrelationID

func WithCorrelationID(id string) Option

WithCorrelationID returns a function that sets the key for the correlationId header.

func WithRequestID

func WithRequestID(id string) Option

WithRequestID returns a function that sets the key for the requestId header.

type TracyGo

type TracyGo struct {
	// contains filtered or unexported fields
}

TracyGo is a struct for the tracy object.

func New

func New(options ...Option) *TracyGo

New creates a new TracyGo object and uses the options on it.

func (*TracyGo) CorrelationIDKey

func (t *TracyGo) CorrelationIDKey() string

CorrelationIDKey returns the underlying correlationID key.

func (*TracyGo) CorrelationIDromContext

func (t *TracyGo) CorrelationIDromContext(ctx context.Context) string

FromContext returns the correlationID from the given context, or the an empty string.

func (*TracyGo) NewContextWithCorrelationID

func (t *TracyGo) NewContextWithCorrelationID(ctx context.Context, correlationID string) context.Context

NewContextWithCorrelationID sets the correlationID to use in the given context. If ctx is nil, a new context without value is created.

func (*TracyGo) NewContextWithRequestID

func (t *TracyGo) NewContextWithRequestID(ctx context.Context, requestID string) context.Context

NewContextWithRequestID sets the requestID to use in the given context. If ctx is nil, a new context without value is created.

func (*TracyGo) RequestIDFromContext

func (t *TracyGo) RequestIDFromContext(ctx context.Context) string

FromContext returns the correlationID from the given context, or the an empty string.

func (*TracyGo) RequestIDKey

func (t *TracyGo) RequestIDKey() string

RequestIDKey returns the underlying requestID key.
