Disable `Non Snake Case` for module name

[kdeconinck]

Hi all,

I don't know if what I'm asking for is actually possible, but I have created a simple struct:

pub struct OpenTypeFontByteSliceReader<'a> {
    buffer: &'a [u8],
    position: usize,
}

Now, I want to bring some structure to my tests, so I would like to have the tests inside a module which has a specific suffix (UTs for unit tests, ITs for integration tests), so I have a module holding unit tests for this struct:

#[cfg(test)]
mod OpenTypeFontByteSliceReaderUTs {
}

Of course, there's a warning when running the tests that the name should be converted to snake case, but then I don't find it readable anymore.

I know that I can apply #![allow(non_snake_case)] to the file, but then the entire file is affected (and the struct with it's implementation is also in this file), and for these functions, I do want the snake case convention.
I can also move this attribute inside the mod itself, so it's only applicable to the module and it's functions, but I would like to only allow the NON snake case names for the name of the module.

Is something like that possible?

I don't think there's a way to do that directly. Best I can think of is re-exporting a snake case mod as a non snake case one using as, like: use non_snake_case_mod as SnakeCaseMod.

By removing the ! the scope is the attached item.

#[cfg(test)]
#[allow(non_snake_case)]
mod OpenTypeFontByteSliceReaderUTs {
}

But that applies the allow to all items within that module as-well, doesn't it?

[erelde]

Yes, but I thought that was relevant to what kdeconinck was asking (and nice thing to learn), since it's a test module I don't see much harm in breaking conventions.

[steffahn]

As far as I understood, OP already tried an approach that put the attribute only on that module

@kdeconinck

I can also move this attribute inside the mod itself, so it's only applicable to the module and it's functions, but I would like to only allow the NON snake case names for the name of the module.

Putting the #![] variant inside instead of the #[] variant outside of the module is AFAIK equivalent, so I guess your suggestion adds some new information regarding syntax, but not too much to solve the problem, over what was already tried.

It seems that it might just be better to stick to the conventions. It would make the code more readable
