Module datadog 

Datadog v1.0 APM trace decoder. Decoder for the Datadog v1.0 APM trace wire format (also called the idx/etp format).

The v1.0 trace API (Content-Type: application/msgpack, endpoint v1.0) sends a tracer payload in a custom MessagePack layout rather than protobuf-over-msgpack. Its defining traits:

• A streaming string table: a string appears once as a literal, then by uint32 index thereafter.
• Structs are maps keyed by field number (uint32), not by name.
• Attribute maps are flat arrays with three slots per entry (key, type, value).
• AnyValue is a uint32 type discriminant followed by the value.

decode_v1_payload decodes one tracer payload into the unified Trace model, producing one Trace per trace chunk. String references are resolved to owned strings during decode.

Enums
