Crate neuron_otel 

OpenTelemetry instrumentation for neuron using GenAI semantic conventions.

Implements ObservabilityHook with the OTel GenAI semantic conventions (gen_ai.* namespace). Emits tracing spans — users bring their own tracing-opentelemetry subscriber for OTel export.

Usage

use neuron_otel::{OtelHook, OtelConfig};

let hook = OtelHook::new(OtelConfig {
    capture_input: false,
    capture_output: false,
});
// Pass to AgentLoop::builder(...).hook(hook).build()

Span hierarchy

Span name	OTel convention	When
gen_ai.loop.iteration	—	Each loop turn
gen_ai.chat	gen_ai.chat	LLM request/response
gen_ai.execute_tool	gen_ai.execute_tool	Tool execution
gen_ai.context.compaction	—	Context compaction

Opt-in content capture

By default, request/response content is NOT captured (privacy). Set capture_input / capture_output to true to include message bodies in span attributes.

Structs
