Overview

Datadog adapter (issue #207, dd-trace-rb). Activates only when ::Datadog::Tracing is loaded. Renames the ACTIVE span Component#action

  • tags it, so the reactive action shows as its own resource in the trace; marks the active span errored on an action-body crash. No-ops with no active span (never opens one itself — that's the app's tracer's job).
