@nnrm_04 I know, I know! It’s been crazy over here with RustConf, etc. I’m planning to blast out a site upgrade this weekend to better handle rich, multi-part articles like Hex Arch has turned into, then I can write freely. Thanks for bearing with me!

Hexagonal architecture is nearly always a good idea.

Hexagonal architecture *in Rust*? That's another level of stability, scalability and test coverage 🚀

Here's my guide to writing ironclad, highly maintainable Rust applications:

@SebasDev1 @alicelovescode It’s in the works! Between RustConf, a new job and some much-needed CMS upgrades, I’ve been strapped for time. My RustConf talk will probably be the next thing to be published, along with the final parts of the hexagonal and error handling articles.

I’m demystifying three macros that underpin 100,000s of Rust applications 👇.

@tomjohnson3 Hey Thomas! I think you’ll find part 4 (out next week) really helpful. It’ll address the relationship between hex arch and microservices in some detail - there’s a lot of overlap and transferrable technique. Thrilled to hear you’re finding the guides useful!

@alexelcu Is this equivalent to saying "don't ruin your presentation with fonts that aren't Times New Roman"? If you don't have an eye for design your presentation will look bad wherever you source your images.

@hexwanderer I'm struggling to think of any use case for this? If you could declare `let x: impl SomeTrait`, this would get compiled to `let x: YourImplementation`, so you might as well just write `let x: YourImplementation`.

@cereal_learner This is very generous feedback ❤️ thank you for motivating me to continue!

@k_pendergrast What other construction do you think would achieve the same tone? 🤔 The intended reading is clear, even if we do have to say a few Hail Marys afterwards.

[Angus - How To Code It @how_to_code_it]

@hexwanderer If you call `fn f(x: impl SomeTrait)` with `StructThatImplsSomeTrait`, it’s compiled to `fn f(x: StructThatImplsSomeTrait)`. This happens for every distinct type that impls `SomeTrait` – multiple copies of the function are compiled (the technical term is monomorphization). [5/5]

[Angus - How To Code It @how_to_code_it]

@hexwanderer To do it generically instead, assign a variable of the concrete type that implements `SomeTrait`, and pass it to functions or structs bounded by `impl SomeTrait`. Be aware: `impl` doesn’t indicate any dynamic dispatch...[4/5]

@kiyov09 Anyone would think I was bitter after years of working in dynamic languages…
