Guice VS rust

Historically, Ports and Adapters was born in the context where Dependency Inversion Principle (DIP) was getting hot, back in the beginning of the 2000’s. DIP was getting more present on development day to day, and an example of a framework that was a pioneer in such topic is Google Guice.

“There are many advantages to using dependency injection, but doing so manually often leads to a large amount of boilerplate code to be written. Guice is a framework that makes it possible to write code that uses dependency injection without the hassle of writing much of that boilerplate code”

This is a common misconception. Guice’s docs delineate between dependency injection as a pattern and Guice as a framework that supports that pattern.

You can (and it's very normal to) use that with new. Dependency injection frameworks (like guice) let you skip passing long parameter lists to constructor arguments like you mention. But you don't really NEED that. They also will solve circular dependency issues and some other things, although a strong argument could be made that you should simply restructure your code so that those issues don't exist.

Bob was a nice guy. We had an overlapping tenure at Google in the 2000s. He was one of the original authors of the Guice dependency injection framework: https://github.com/google/guice. When I was earning Java readability at Google, I was fortunate to have had him assigned as a reviewer. Huge loss; he left a very positive impression on me.

He was fairly well known figure in the Java world. RIP.

Usually each context has a different scope and lifetime associated with it. Here, it sounds like there are two distinct scopes: server and request (cf. how Guice models scopes: https://github.com/google/guice/wiki/Scopes). It is rarely sensible to merge the scopes or contexts together. If we think about a context, it contains several things:

using libraries from java world, such as Guice;

As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.

If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Here's an example of someone citing a disagreement between CRT and shell32:

https://github.com/rust-lang/rust/issues/44650

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:

https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html

Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

    #include 

> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.

Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Almost fixed the compiler: https://github.com/rust-lang/rust/pull/123325

Rust: A secure, efficient, and modern programming language (omitting ten thousand words). You can simply follow the installation instructions provided on the official website.

Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.

To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.

The above Assert<{N % 2 == 1}> requires #![feature(generic_const_exprs)] and the nightly toolchain. See https://github.com/rust-lang/rust/issues/76560 for more info.
