# Logging: Request IDs and Access Logs
#
# request_id — ensures every request has a correlation ID.
#   Forwards client-supplied IDs; generates one when absent. Echoed in
#   the response. The header_name field controls which header is used
#   (defaults to X-Request-ID).
#
# access_log — structured log line per request (method, path) and
#   response (status). Enable with RUST_LOG=info.
#
# Both placed before the router so they run on every request.
#
# Usage:
#   RUST_LOG=info cargo run -p praxis-proxy -- -c examples/configs/observability/logging.yaml
#   curl -v http://localhost:8080/api/users
#   curl -H "X-Trace-Id: my-trace-42" -v http://localhost:8080/
