Module telemetry 

Agent-level observability — OpenTelemetry tracing, structured logging, Prometheus metrics.

Mirrors the wire crate’s telemetry layer but for agent lifecycle operations. All components are feature-gated for zero overhead when disabled:

• tracing-support: OTel spans and structured logging
• metrics: Prometheus metric definitions

Re-exports

pub use setup::TelemetrySetup;

Modules

logging

Structured logging helpers for agent lifecycle.

metrics

Prometheus metric definitions for agent lifecycle — counters, histograms.

setup

OTLP exporter setup helpers for agent-level telemetry.

spans

OpenTelemetry span definitions for agent lifecycle operations.

Structs

TelemetryMiddleware

Auto-registered middleware that calls telemetry functions. Zero-overhead when tracing-support and metrics features are disabled (all telemetry functions compile to no-ops).
