Is this something you experience when writing your code, or is this something you experience when reading other people's code?
If it's the former, I'd really love to hear more about those experiences.
If it's the latter, are there particular features that crop up that make code feel like too much?
(To be clear, Rust isn't perfect for everyone, despite our best efforts. And if you want to work with another language, you should! I'm not looking to defend it; your experiences are valid. We'd love to make Rust better, so I didn't want to miss the opportunity to ask, because we so rarely hear from people in the intersection of "I love Rust" and "Rust is too much".)
I feel like my biggest struggle is simply how hard (tedious?) it is to properly work with generics and some more complex applications of traits. Any time I am working with (especially writing, somehow reading is easier) these, I always take an ungodly amount of time to do anything productive.
I am almost certainly sure this is a skill issue -- I am simply not "Rusting" like I am supposed to. Maybe I overuse generics, maybe I rely on traits too much, maybe I am trying to abstract stuff away too much. But this is one of the reasons I want to also explore other languages in the space, especially ones which make it impossible for me to make this so complex.
Don't get me wrong -- all of this complexity is a joy to work with when I can use my brain. But sometimes, it's just too much effort to do stuff, and it feels like I could be getting away with less. Curiously, I never had a problem with the borrow checker, even though people often complaining about how much it forces them to "stop and think".
Another thing is that C, for some weird reason, always feels "lower level" than Rust, and seeing it gives me some sort of weird satisfaction that Rust does not. Maybe it's just a greener grass syndrome, but wanted to mention it nonetheless.
All this said, I want to just emphasise, that despite this shortcoming (if it even is one), if I were forced to choose a language to spend the rest of my life with, I would not be the least bit sad to only ever use Rust again. I absolutely love it.

Is this related to the problem where, if you want to put a generic in a data structure (e.g. an implementation of `Write`), you find yourself propagating a generic bound up an entire hierarchy of data structures and functions using those structures?
Asking because one thing that's common amongst Rust developers is a bit of an aversion to using `dyn Trait` types, and using a `Box<dyn Write>` (for instance) in the right place can wildly simplify your program.

The next times you find this feeling arising, please feel free to reach out, if you'd like; I would genuinely love to hear about it. You can reach me by DM on the Rust Zulip, or by the email in my profile.

I was originally a C developer, and I can sympathize. I don't tend to crave that "lower level" feeling often, but for me, there was something satisfying about C in the old DOS days, where you could make a pointer to video memory and scribble on it.

And I did exactly that. I did eventually get around to using dyn Write, but that still gave me headaches because of how I cannot use impl Write as a result type in closures, which I need to do if I want to use tracing_subscriber::fmt::with_writer() and pass in these trait objects.
Despite being this close to the solution, I somehow again wound up propagating generics back at least four functions.
I ended up not writing any generic-based stuff and resigned to just manually writing each type's implementation out, but I am going to tinker with this again today. Hopefully, I can use your advice.
Thank you so much for taking the time to write this. Means a lot!

Exactly.
I hope we manage to fix that! We're working on making `impl Trait` usable everywhere a type works. I'll check where "return type of a closure" is on the `impl Trait` radar.

Thank you as well for taking the time to fill in more details!
I think even moreso I can understand the sense of Rust feeling too large not because the language itself is, but because there are SO many of these neat tricks and little utility functions that are necessary to express what you want, and it's quite impossible to remember each and every one and how to go back and find them later.

Indeed. This is brilliant.
I never worked with low level languages except some university lession, but I think I have good general understanding how a CPU and memory works (just for some context)
But even for educational purposes, using a language with a poor selection of libraries is likely to lead to a bad experience if what you want to produce is working, non-trivial software. Every project includes some "boring" aspects -- such as parsing configuration and data files -- that you won't necessarily enjoy writing from scratch. The overall programming experience is shaped by much more than the design of the language alone.
One thing that's important to notice, I think, is that low-level languages' combined market share has fallen sharply since the 1970s, and it doesn't seem that the trend is about to sharply reverse direction. To me that suggests that if a low-level language wants to be more popular than C++, it should focus on low-level programming and shouldn't try to also be a good applications programming language (as C++ has tried to do that, but the overall market share of C and C++ is lower now than it was in, say, 1990), but I could be wrong about that.
UnsafeCell I find particularly useful to exponentially decrease the amount of boilerplate needed to convince the compiler that your code is safe.
