To handle errors explicitly in TypeScript, you can apply Rust-inspired Result types to make failure paths visible, forcing the caller to handle both success and error outcomes instead of relying on exceptions.

Eliminating impossible states in TypeScript is achieved by applying discriminated unions, which enforce exhaustive type checks and structurally prevent invalid data combinations at compile time.

Validating data at the TypeScript system boundary involves checking inputs once upon entry, ensuring internal code processes only trusted data for improved reliability and safety.

Yes, this approach to TypeScript code safety integrates with validation libraries like zod and yup to validate data at the boundary and enforce system reliability.

Use Rust-inspired patterns in TypeScript when developing new applications or refactoring legacy code that requires high safety, explicit error handling, and strict maintainability standards.
