diplomat VS crates.io

The tooling for the first kind -- calling Rust from another language -- is a bit less developed, and tends to rely on code generation that doesn't necessarily produce a natural C API. cbindgen, uniffi, cxx, and Diplomat all take this course.

I don't think that accurately describes what ICU4X does. It generates code directly in the language needed using Diplomat. Which currently supports JS/TS/Wasm, C, C++, and .NET, but we plan to support more (Dart is actively being worked on, there is a lot of interest in Java). Diplomat is designed to be relatively easy to write backends for: you have to write code that converts its internal IR to bindings code, so you mostly need to understand that internal IR and figure out how to idiomatically map it to other languages.

The ICU4X team is developing diplomat - https://github.com/rust-diplomat/diplomat/

I'm not that interested in a separate tool for this but it would be really cool to have a dart plugin as a part of Diplomat. Diplomat's not fully polished yet but it's totally okay to add new language backends to it. (Eventually I plan to restructure it so that it has a cleaner plugin interface, but for now "checked into tree" is fine for backends)

Rust has a rich ecosystem of frameworks and libraries that let you read, parse, and manipulate text files, interact with cloud services and databases, and perform any other job that your project's development workflow may require. And because of its strong typing and tight memory management, you are much less likely to write programs that behave unexpectedly in production.

All the code discussed in this article can be accessed through this repository. For integration with existing projects consider using keyword_extraction crate available on crates.io.

So, be sure to double-check your critical libraries and be sure their alternatives exist in the Rust ecosystem. There’s a good chance the crates you need are available in Rust's crates.io repository.

The previous section was very simple, this section is also very simple but introduces us to cargo which is Rust's package manager, as a JS dev my mind goes straight to NPM.

Now, there has to be a place where all these packages come from. Similar to npmjs registry, where all node packages are registered, stored and retrieved, Rust also has something called crates.io where many helpful packages and dependencies are registered.

Before proceeding, let's check https://crates.io/, the official Rust package registry.

The most thrilling aspect has been the joy of writing the backend. It's like every struct, enum, and method in Rust forms this interconnected Multiverse of code , which you can see in crates.io which is best Documentation experience I Ever Had.

5. Crates.io

When using crates from eg. crates.io, and also things like std and core

Vendoring your packages was very tedious to even remotely get to work with Cargo. I spent a very long time getting Cargo to work together with cargo-local-registry. We vendor crates from crates.io and a custom internal registry.
