MetrixWire.Config (MetrixWire v0.2.2)

Copy Markdown View Source

Resolved configuration. Built once at application boot from config :metrixwire, ... merged with ENV fallbacks (METRIXWIRE_KEY, METRIXWIRE_ENDPOINT, METRIXWIRE_ENABLED). Nothing here throws — bad input degrades to a sensible default so instrumentation never breaks the host app.

Held in :persistent_term for lock-free, low-cost reads from the hot path (every telemetry event reads config).
