Documentation

Overview

Package otel provides thin OpenTelemetry helpers for Loom gRPC servers and clients.

The package intentionally wraps the official OpenTelemetry contrib gRPC instrumentation rather than implementing tracing itself. Applications remain responsible for configuring the tracer provider, exporter, and resource attributes; Loom owns the transport seam so generated and hand-written gRPC services can share one instrumentation path.

Use ServerOption and ClientOption with grpc.NewServer and grpc.NewClient (or grpc.Dial):

server := grpc.NewServer(otel.ServerOption())
conn, err := grpc.NewClient(target, otel.ClientOption())
