My Tiny Rust Utils, Part 5: mod.rs
icsboyx · 2026-05-01 · via DEV Community

This last part is about the least impressive file in the folder:

pub mod helpers;
pub mod macros;
pub mod save_load;
pub mod web;

Enter fullscreen mode Exit fullscreen mode

That is src/utils/mod.rs.

It is just four lines.

And maybe that is why it feels like the right place to end the series.

Why a boring file still matters

I like this file because it does not pretend to be smarter than it is.

It just says:

  • these are the utility modules
  • they live together
  • this is the shape of the toolbox

After the previous parts, that shape is easier to read:

  • macros.rs helps me see what the program is doing
  • helpers.rs removes a bit of error and JSON friction
  • save_load.rs gives me one place for config-like persistence
  • web.rs keeps HTTP glue from leaking everywhere

None of those files is huge.

None of them is a framework.

That is very intentional.

I think I work better when the code is allowed to stay small and honest for as long as possible.

How the folder feels to me

This utils folder is not something I built because I wanted to be abstract.

It is something I built because I know how I work.

If I do not create a little structure around repeated pain points, I end up with the same code copied in slightly different ways across the project.

And then I get annoyed with myself later.

So this folder is a compromise between two things:

  • I do not want ceremony
  • I also do not want chaos

That is really the whole story.

A more personal ending

I think this is the part where I should be honest.

For me, coding is not really "work" in the emotional sense, even when it is tiring.

It is more like a mix of:

  • joy
  • frustration
  • curiosity
  • stubbornness

Sometimes it is fun.

Sometimes it is painful in a very specific and ridiculous way.

Sometimes a tiny bug ruins half a day.

Sometimes a four-line helper makes the whole project feel lighter again.

That is why I keep doing it.

Not because every line of code is important.

Not because every project needs to become a product.

But because coding, for me, is still one of the nicest forms of mental exercise I know.

It is a hobby, a habit, and occasionally a headache I choose on purpose.

And honestly, I mean that in a good way.

Final thought

If you also keep building small local utility files for your own projects, I do not think that is a bad sign.

Maybe it just means you are slowly learning what kind of friction bothers you, and what kind of tools help you think.

That is more or less what this folder is for me.
