# tracer

Example of using gin-gonic/gin.

```go

import (

	"net/http"

	"github.com/gin-gonic/gin"

	"github.com/itsubaki/tracer"

)

func SetTraceID(c *gin.Context) {

	value := c.GetHeader("X-Cloud-Trace-Context")

	xc, err := tracer.Parse(value)

	if err != nil {

		c.AbortWithStatus(http.StatusInternalServerError)

		return

	}

	c.Set("trace_id", xc.TraceID)

	c.Set("span_id", xc.SpanID)

	c.Set("trace_true", xc.TraceTrue)

	c.Next()

}

```

```go

import (

	"net/http"

	"github.com/gin-gonic/gin"

	"github.com/itsubaki/tracer"

	"go.opentelemetry.io/otel"

)

var tr = otel.Tracer("mypackage/myfunc")

func Func(c *gin.Context) {

	traceID := c.GetString("trace_id")

	spanID := c.GetString("span_id")

	traceTrue := c.GetBool("trace_true")

	parent, err := tracer.Context(c.Request.Context(), traceID, spanID, traceTrue)

	if err != nil {

		c.Status(http.StatusInternalServerError)

		return

	}

	func() {

		_, s := tr.Start(parent, "something to do")

		defer s.End()

		...

	}()
