// Package opencensus provides a migration bridge from OpenCensus to
|
|
// OpenTelemetry. The NewTracer function should be used to create an
|
|
// OpenCensus Tracer from an OpenTelemetry Tracer. This Tracer can be use in
|
|
// place of any existing OpenCensus Tracer and will generate OpenTelemetry
|
|
// spans for traces. These spans will be exported by the OpenTelemetry
|
|
// TracerProvider the original OpenTelemetry Tracer came from.
|
|
//
|
|
// There are known limitations to this bridge:
|
|
//
|
|
// - The AddLink method for OpenCensus Spans is not compatible with the
|
|
// OpenTelemetry Span. No link can be added to an OpenTelemetry Span once it
|
|
// is started. Any calls to this method for the OpenCensus Span will result
|
|
// in an error being sent to the OpenTelemetry default ErrorHandler.
|
|
//
|
|
// - The NewContext method of the OpenCensus Tracer cannot embed an OpenCensus
|
|
// Span in a context unless that Span was created by that Tracer.
|
|
//
|
|
// - Conversion of custom OpenCensus Samplers to OpenTelemetry is not
|
|
// implemented. An error will be sent to the OpenTelemetry default
|
|
// ErrorHandler if this is attempted.
