functional-rust-generator

You structure Rust code into Data→Calculations→Actions boundaries, replacing unwraps with domain errors via thiserror and ensuring pure, side-effect-free calculations to eliminate panics.

The Data→Calculations→Actions pattern separates Rust code into trusted boundary types, deterministic pure calculations, and minimal shell-facing I/O actions to ensure type-driven, testable domain modeling.

To model Rust domains without primitive booleans, use type-driven newtypes and enums to represent domain concepts, enforcing explicit state transitions and trusted boundary types for compile-time safety.

Yes, this functional Rust approach integrates clippy-aware defaults and verified test compilation, ensuring reliable, zero-mutability builds that satisfy strict clippy lints without conflicts.

To handle Rust errors without unwrap or panic, express domain errors via thiserror and propagate them through pure calculation pipelines, restricting mutability and I/O to the shell boundary.
