Module trace 

OpenTelemetry-compatible trace collector for debug sessions.

Collects span data during an agent session and serializes to OTLP JSON format at session end. All text-bearing attributes are redacted via crate::redact::scrub_content before storage (C-01).

Design notes:

• Uses explicit begin_X / end_X methods with owned SpanGuard — safe across async .await boundaries because no borrow to TracingCollector is held (C-02).
• A HashMap<usize, IterationEntry> tracks concurrent iterations (I-03).
• Drop on TracingCollector flushes partial traces on error/panic paths (C-04).
• When the otel feature is enabled an mpsc channel forwards completed spans to the OTLP exporter in tracing_init.rs (C-05).

Structs

LlmAttributes

Attributes for a completed LLM request span.

MemorySearchAttributes

Attributes for a completed memory search span.

SpanData

A completed span ready for OTLP serialization.

SpanGuard

Owned guard returned by begin_* methods. Pass back to end_* to close the span.

ToolAttributes

Attributes for a completed tool call span.

TraceEvent

Event sent over the mpsc channel to the OTLP exporter.

TracingCollector

Enums

SpanStatus

Span status code (matches OTLP StatusCode values).

Functions

serialize_otlp_json

Serialize spans to OTLP JSON Protobuf encoding.
