OpenCensus Binary Format Propagation for Node.js

OpenCensus Binary Format Propagation sends a span context on the wire using binary encoding, allowing other services to create spans with the right context.

The library is in alpha stage and the API is subject to change.

• removing Tracer's startChildSpan(name?: string, kind?: types.SpanKind) interface

Old code

// Multi argument interface
const span = tracer.startChildSpan('my-span', types.SpanKind.SERVER);

// Or options object interface
const span = tracer.startChildSpan({
  name: 'my-span',
  kind: types.SpanKind.SERVER
});

New code

// Only options object interface is supported
const span = tracer.startChildSpan({
  name: 'my-span',
  kind: types.SpanKind.SERVER
});
