Overview ¶
Package trace encapsulates a module which contains the entirety of the trace-agent's processing pipeline. The code may be reused to process traces in the same way that the Datadog Agent does, but outside of it.
Please note that the API is subject to major changes and should not be relied upon as being stable.
