antithrow

A TypeScript ecosystem for Rust-style Result<T, E> error handling without exceptions.

antithrow helps you model failure paths explicitly so error handling is type-safe, composable, and visible at compile time.

• Keep the happy path readable while still handling failures early.
• Encode all failure variants in the type system.
• Compose sync and async pipelines with the same mental model.
• Interoperate with throw-based code via Result.try(...).
