¶
Adds support for goroutine-based propagation of contexts to OpenTelemetry tracing.
This library is inspired by https://github.com/tylerb/gls and https://github.com/jtolds/gls.
Example
topCtx, top := tracer.Start(context.Background(), "top")
// two will be a child span of top
_, two := tracer.Start(topCtx, "two")
// three will be a chlid span of two
_, three := tracer.Start(trace.CurrentContext(), "three")
// four will be a child span of three
_, four := tracer.Continue("four")

Functions ¶
func CurrentContext ¶
CurrentContext returns the current goroutine-local context, or context.Background() if there is no current context.
Types ¶
type Tracer ¶
type Tracer interface {
trace.Tracer
// Continue is like Start, but starts the new span using the context from CurrentContext().
Continue(spanName string, opts ...trace.SpanStartOption) (context.Context, trace.Span)
}
Tracer wraps trace.Tracer to support goroutine-bound context propagation.
