Crate hwhkit_observability 

Logging + tracing setup for hwhkit services.

• init_logging accepts format = "auto" | "json" | "pretty". auto picks JSON when stdout is not a TTY (production / containers) and pretty when running interactively.
• With the otel feature enabled, otel_layer::init_with_otel wires an OTLP gRPC exporter into the tracing subscriber so every span is shipped to the configured collector.
• All public init functions return ObservabilityError; the crate has no remaining Result<_, String> surface (project-wide policy as of 0.6).

Modules

otel_layer

OpenTelemetry-aware initialiser, gated on the otel feature.

redis_instrument

OpenTelemetry instrumentation helpers for the redis crate.

reqwest_instrument

Minimal OpenTelemetry instrumentation middleware for reqwest.

sqlx_instrument

Lightweight OpenTelemetry instrumentation helpers for sqlx.

Structs

LoggingConfig

Standalone logging configuration for callers that drive init_logging directly without going through the hwhkit_config::AppConfig pipeline.

OtelConfig

Standalone OTLP/OTel configuration for callers that drive otel_layer::init_with_otel directly. Mirrors hwhkit_config::OtelConfig.

Enums

ObservabilityError

Error returned by the public initialisation entry points (init_logging, otel_layer::init_with_otel).

Functions

init_logging

Initialize tracing logging without OTel. Safe to call once per process.
