Functions ¶
func CheckSetDefaultTextMapPropagator ¶
func CheckSetDefaultTextMapPropagator()
CheckSetDefaultTextMapPropagator checks if the default TextMapPropagator is set.
func GetBaggageMap ¶
GetBaggageMap gets and returns the map of baggage values.
func GetBaggageVar ¶
GetBaggageVar gets and returns the value of the specified key from baggage.
func GetDefaultTextMapPropagator ¶
func GetDefaultTextMapPropagator() propagation.TextMapPropagator
GetDefaultTextMapPropagator returns the default TextMapPropagator for context propagation.
func GetTraceID ¶
GetTraceID gets the trace id from the context.
func IsUsingDefaultProvider ¶
func IsUsingDefaultProvider() bool
IsUsingDefaultProvider checks if the default trace provider is used.
func SetBaggageMap ¶
SetBaggageMap is a convenient function for adding multiple key-value pairs to baggage.
func SetBaggageValue ¶
SetBaggageValue is a convenient function for adding a key-value pair to baggage.
func WithTraceID ¶
WithTraceID injects a custom trace id into the context.
Types ¶
type Baggage ¶
type Baggage struct {
// contains filtered or unexported fields
}
Baggage is a mechanism for propagating key-value data in a distributed system. It allows attaching custom data (such as user ID, request ID, etc.) to traces and propagating them across service calls.
func NewBaggage ¶
NewBaggage creates a new Baggage instance.
