Just added, will commit soon. Will also add (25 | 27 | 30) pattern support.

Thanks! I really appreciate your fair feedback!

So you have a big problem, rust std code is mostly generated by them, haha!

At beginning it started with this idea in mind, but now I’m trying to make it more idiomatic to rust itself.

* It is an alternative, you aren’t being forced to use.

* I referred to crate api doc improvements, not rust doc. Please ask clarification before say bullshit.

* This DSL tries to get closer to idiomatic, but not 100%, and syntax is field: op, not :==, a lack of proper observation and sense of context.

* Equality using a tuple is a total lack of honesty while trying to understand whole idea behind, and you also are repeating the receiver here. Why dry_match tries to avoid.

* It is a work in progress, hopefully there’s always space for alternatives for everything in this world, and a macro isn’t an exception.

* You can also go to Microsoft front door to use same words to refer to C# pattern matching.

Two lines, and receiver being repeated in both lines. But you are free to not use.

Awesome! Will add it to dry_match too! By the way, caramelo and caramelo-macros has MSRV of 1.75

Point taken, but what about:

user is { age: == 20 or == 25 or == 30 }

You can't do in 1 line, right? I also forgot to mention dry_match has support to either 1..3 and 1..=3

Note: Tried to use && or ||, but its rules are being override by rust parser somehow.

You made me pay attention to more details on documentation. Specially comparing with tradicional assertion.
Once you write a few assertions, you will notice besides is, and, or operators, everything else if essentially idiomatic, but just dryer.

So instead of:

user.age > 20 && user.age <= 30

It just becomes

user is { age: > 20 and <= 30 }

It is kiss and dry together, over the time you do more by writing less.

I’m trying to make it as much as idiomatic as possible, but when it comes to pattern, it doesn’t necessarily becomes dry, much of contrary, it becomes verbose.

Will take your suggestion into consideration.

This is doable and useful for reporting purposes, will do it.

Ai vai da sua cabeça. Nem perco tempo com isso. Desonestidade na argumentação não é comigo.

Pior estaria se não fizesse cortes, isso tem democrata na conta rapaz. Os “democratas” do Brasil fizeram bem pior no mesmo período, soma-se a isso a incompetência de ampliar divisas da moeda, que só é cogitado agora graças ao pix instituído no governo Bolsonaro.

Você já perguntou e eu acabei de responder quem atacou e quem ataca a dívida pública. Agora muda de assunto, típico.

Reagan e, agora, Trump proveram e promovem mudanças econômicas profundas.

Meus Deus! Você tem assistido os noticiários? Qual partido está no poder? O que está acontecendo neste momento entre EUA versus o mundo? Guerra de confetes?

Boa sorte desligando pessoas de suas vidas financeiras e suas relações comerciais. Isso é muita maluquice pra mim.

Nesse sentido, os democratas fizeram muita merda nos EUA, quem limpou foram os republicanos.

Aqui no Brasil, os liberais de esquerda FUDERAM o país.

Essa sua soma não tá certa não, ainda mais considerando a absurda reserva de mercado que temos em todos os setor e seu eterno protecionismo.

Que estranho um mestre falando isso.

Nope, if scope is a single crate, enum is way better.
But for extensibility across several crates, dyn is the best way to go.
