func (c *Config) MergedSpanStartOptions(opts ...trace.SpanStartOption) []trace.SpanStartOption
MergedSpanStartOptions returns a copy of opts with any DefaultStartOpts that c is configured with prepended.
func (*Config) ResolveTracer ¶
ResolveTracer returns an OpenTelemetry tracer from the appropriate TracerProvider.
If the passed context contains a span, the TracerProvider that created the tracer that created that span will be used. Otherwise, the TracerProvider from c is used.

Apply(*Config)
}
Option applies options to a configuration.
func WithAttributes ¶
WithAttributes returns an Option that appends attr to the attributes set for every span created.
func WithPropagator ¶
func WithPropagator(p propagation.TextMapPropagator) Option
WithPropagator returns an Option that sets p as the TextMapPropagator used when propagating a span context.
func WithTracerProvider ¶
func WithTracerProvider(tp trace.TracerProvider) Option
WithTracerProvider returns an Option that sets the TracerProvider used for a configuration.
