Rust-Inspired Typescript
summary
Rust habits mapped to concrete TypeScript patterns: make impossible states explicit with discriminated unions and exhaustive never checks, return Result-like types instead of throwing using better result, validate unknown edges with runtime schemas like Zod and domain-wrapped IDs, and signal local mutation intent by separating mutable from readonly shapes (borrow-vs-mutate mindset). A surprising practical datapoint: the codebase totals quarter million lines of TypeScript, and examples show V+ as a unified toolchain alternative.
