What is ice?

ice is a set of composable reliability primitives for Go — retries, circuit breakers, bulkheads, fallbacks, and timeouts — that wrap risky operations. Designed and maintained by Loa so the behavior, API, and feature set stay under our control rather than inherited from a third-party dependency.

The name is a nod to ICE (Intrusion Countermeasures Electronics) from William Gibson's Sprawl trilogy: the defensive software wrapping valuable systems.

Features

Under active design. Components will be documented as they land.

Planned primitives, composable in any order:

• Retry — re-run transient failures with configurable backoff
• Breaker — trip open under sustained failure, reject fast
• Bulkhead — cap concurrency, reject fast when saturated
• Fallback — substitute a safe response or alternate path
• Timeout — bound latency per call
