Rust Result in TypeScript

The EarthBucks library is co-written in both Rust and TypeScript. It includes an implementation of all basic data structures including transactions and blocks with standard test vectors. Implementing everything in both languages has been very informative. It is clear the Rust Result enum for handling errors is superior to exceptions in TypeScript. As such, I have decided to change all error handling in TypeScript to use the ts-results library in node.js which is a TypeScript implementation of Rust’s Result enum.

I had issues getting ts-results to build in vite for the webapp, so the code for ts-results has been ported directly into the TypeScript library. I plan to use this pattern not just for the internals of the library, but also the external interface, and to even mimic this pattern for the RPC interface to be used by the peer-to-peer network and third-party apps.
