instrumentation library

The surface an integration package is built on. Not for application code.

Separate from inoxth_edot_flutter.dart on purpose. An app instruments its requests with EdotHttpClient or the Dio interceptor and never needs anything here; a transport integration needs EdotRequestTrace, and it has to be public for the Dio package to reach it at all, because that package ships separately (ADR-0010) and Dart has no visibility between packages.

@internal cannot say this: it would make every use from the Dio package an analysis failure, which is the one use it exists for. A second library says it instead — importing this is a deliberate act, and it keeps the surface an app developer reads as small as it was.

See ADR-0013 for what an integration built on this must honour.

Classes

EdotRequestTrace

One outbound request being traced, whatever transport made it.
