Self-Healing State Machines: Resilient State Transitions in Go

Distributed systems are inherently stateful. Whether you're managing a database connection pool, a multi-step payment workflow, or a complex IoT device lifecycle, you need to transition between states reliably. Standard state machines (FSMs) are great for logic, but they are often brittle. What happens if a transition involves a network call that fails? Most developers end up wrapping their machine.Transition() calls in manual retry loops, cluttering their business logic and losing visibility into why a transition failed. Inspired by Erlang's gen_statem behavior, Resile introduces resile.StateMachine : a standardized, resilient state machine where every transition is inherently protected by resilience policies. The Resile Way: One-Line Resilience for Transitions With resile.StateMachine , you don't just define how to move from State A to State B. You define a Resilient Transition . Here is how you implement a self-healing connection manager: import "github.com/cinar/resile" // 1. Defin
