Observability overview

These crates build on each other:

1. observability_core — ports, adapters, ObservabilityManager, W3C trace context, batching.
2. observability — facade (Obs, ObservabilityConfig) and optional integration with the otel and prometheus workspace crates.
3. structured_logging — optional convenience and performance layers on top of observability_core.
4. otel — OpenTelemetry-specific types (Otel, OtelManager, OTLP client, sampling).
5. prometheus — Prometheus-specific types (Prometheus, PrometheusManager, federation/cardinality when enabled).

Feature flags and public exports are defined in each crate’s Cargo.toml and src/lib.rs. Use those as the source of truth; this site summarizes them and does not replace cargo doc.

observability_core Ports, adapters, ObservabilityManager, W3C trace context, batching.

observability Facade — Obs, ObservabilityConfig, optional OTEL and Prometheus integration.

structured_logging Enhanced structured logging with performance optimizations and convenience APIs.

otel OpenTelemetry integration — OTLP helpers, sampling, resource attributes.

prometheus Prometheus metrics — registry plugin, federation, push gateway, cardinality reduction.
