ETDL — Event Tree Definition Language Compiler

A Rust compiler and runtime for the ETDL specification.

ETDL is a declarative, design-time DSL for reliability-aware, event-driven business processes. It models causal sequences as event trees (IEC 62502) and failure probabilities as fault trees (IEC 61025).
