Functions

func CloseSpan

func CloseSpan(span trace.Span, err error)

CloseSpan closes a span and records the given error if not nil. If the span is nil, this is a noop.

func StartSpan

func StartSpan(ctx context.Context, tracer trace.Tracer, name string, opts ...trace.SpanStartOption) (context.Context, trace.Span)

StartSpan will start a span using the tracer on input. If the tracer is nil, the context returned is the same as on input, and the span will be nil.
