Clean Observability in Rust: OpenTelemetry + Jaeger

Observability should not pollute your domain. In this episode of Fearless in Rust, we implement structured tracing in RustPulse using OpenTelemetry and Jaeger — the hexagonal way. The goal: Get real, end-to-end traces from HTTP → use case → repository Without coupling the core domain to infrastructure. You’ll learn: • How to build an OTLP exporter in infrastructure • How to conditionally enable tracing via environment variables • How to wire tracing layers at the composition root • How to create HTTP boundary spans via middleware • How to instrument use cases (not just handlers) • How to run Jaeger locally and inspect traces • The difference between logging and true observability We keep the core clean. We export only at the edge. We make the system observable without breaking architecture.

If you're building serious Rust backends, distributed systems, or preparing for protocol/blockchain engineering, this is foundational.
