A TypeScript library implementing Rust's Result and Option types, bringing compile-time error checking and explicit optional values to TypeScript. It provides Ok/Err and Some/None variants with combinators like map, andThen, and Result.all, plus rxjs integration helpers.

Use cases

• handle errors without exceptions in typescript
• make nullable values explicit with an Option type
• force callers to check for failure at compile time
• chain fallible operations with map and andThen
• combine multiple results with Result.all or Result.any
• replace string | undefined returns with typed optionals

When to choose

• you want Rust-style explicit error handling in a TypeScript codebase
• your team wants compile-time enforcement of error and null checks
• you use rxjs and want result-aware operators

When to avoid

• you prefer idiomatic TypeScript with exceptions and union types
• your project is very small and the extra abstraction adds overhead
• you need a full functional programming toolkit rather than just Result/Option
