- Maybe I'm not that deep into programming, but I don't understand the hype about Zig?
I programmed in rust a bit and can't say I'm an expert, but in my view rust mostly-solved the memory management problem at compile time and without a GC, and it works very well. The biggest con and cost I've always seen repeated so far is that "it's slow to compile", and I get that, if you're past 250 crates the final --release link tends to become noticeable, but there were improvements to incremental compilation.
On the other hand - looking at the syntax from this post - Zig feels a blend of javascript, python and golang syntax that still requires memory management. So a nicer-written C that inherits all the issues from C? From the post: no functional programming, data mutation, memory leak, double-free, memory corruption.
Personally I'd rather trade a couple minutes of final link every time when this is the other option.
by plqbfbv - > Rust: Drop runs automatically at scope end, so this specific bug simply doesn’t exist.
That's why having no auto-destructors is a dead-end. This is the greatest mistake of such languages like Zig or Odin.
by Panzerschrek - > Zig, by comparison, offered little beyond syntax highlighting and basic autocompletion.
Zig has a language server and "The majority of LSP features are supported" (https://github.com/zigtools/zls#features).
- “ The language is different from Rust (who could’ve thought that, yeah), but it left a genuinely good impression. It’s straightforward, modern, and blazingly fast. I believe it has real potential to become the true successor to C. On the other hand, it’s still young, and it shows: the shape of the language itself feels unfinished in places, and I suspect it’ll pick up more of the cooler quality-of-life features and syntax sugar as it matures.
As for me, I’d like to keep contributing to the ecosystem, and I will, whenever I come across a project worth building.”
Idk I don’t write either well enough to have a hand in this but losing out all of this for more Imperative stuff seems like a step back.
“ No functional paradigm
Rust is technically an imperative language, but it draws heavily on functional concepts: zero-cost iterators, lazy evaluation, ADTs, pattern matching, monadic types, traits, closures, and so on. Having also spent time with Haskell and Erlang, I’ve become fairly inclined toward the functional style, and it shows in this library. It leans heavily on FP idioms:
Monadic error control via combinators like Queryable and related types Monadic-style data types like Data<T> with map, flat_map, reduce, and friends Pure, immutable transformations Combinators over iterators instead of loops Closures for local abstraction Declarative macros as a small embedded DSL Sum types and product types”
by gigatexal - One of the section headings says "Mutation vs. immutable monad is the core difference" but this is not true.
The code in that section is clear in its purpose and broad outline: "Give me a function and data; if the data is bare apply the function to it; if the data is a container apply the function to each item inside it."
You can absolutely do that with immutable data structures in Zig. You just have to pass an allocator to the function (i.e. instead of calling data.flat_map(f), you call data.flat_map(a, f) where a is your allocator).
That the Zig version of the code does mutation is a matter of programmer choice, not something imposed by the language.
(Also, what do monads have to do with it?)
by csense - Two additional points:
1. Tooling (as an extension to the mentioned IDE support point). Zig and Rust are both praised for their tooling and I think rightfully so. The C/C++ interop story and the cross-compiling story in Zig are great. From the standpoint of a working practitioner though I think Rust is way ahead. Not surprising given that Zig is much younger, but something to keep in mind.
2. Compile Time Stuff: Here Zig is praised and Rust not so much. I think this is undeserved. Rust has much higher aspirations for their compile time features, namely that outcome must be identical regardless when the code runs. This is a very useful property but makes the task much harder and fundamentally incomparable with Zig comptime.
by weinzierl - For various purposes I work on a language comparison project that includes C and candidate successors such as Go, Zig. One question is the language to use for an archival port of a 1980's computer algebra system written in 32-bit K&R C. While Zig is a great debugging compiler, it's not yet stable enough to be the best target language for archival purposes.

So you're in a restaurant where you don't speak the language, you can't read the menu, but you see three price points for set meals featuring the house specialty. (Say, "Crossing the Bridge" noodles in Yunnan.) Which do you choose? My tour guide, the author Fuchsia Dunlop, later agreed with me this is obvious: The middle choice.
So you're choosing between Go and C23 as candidate successors to K&R C. They both have "royal blood". One got the name. Knowing nothing more, which do you choose?
The answer is equally obvious. The one that got the name also got the warts.
by Syzygies - Personally while I'm somewhat pragmatic about Rust, I do have to admit it fills a niche that no other language does currently: that of a high-performance, zero runtime memory-safe language.
By memory-safety I mean the basic 'no crashes and corruption' version, that's fulfilled by Java, Go etc., but not by C++ and Zig.
I'm a C++ dev among other things, and I have enough experience to know, you really can't hand C++ to a novice dev (even one who uses smart pointers correctly), and expect an app with no memory related crashes/issues.
For this reason only, I generally thing C/C++/Zig is a language for typical professional projects/applications (which are written usually in GC languages nowadays).
I think it's a hard cutoff criteria. Most programmers/orgs simply cannot work with memory unsafe software. Most commerical C++ codebases leak.
This is basically the most important and common 'niche' of SW dev, which for some reason has been somewhat neglected, and I don't really consider Rust a great fit here either, but it doesn't lack anything that would disqualify it.
Swift would be another good choice, but it seems that language is very tied to the Apple ecosystem.
The only (non-Apple) language that understood EXACTLY what these people wanted imo was Object Pascal/Delphi in the 90s to early 2000s but seem to have died out unfortunately.
