Sorry for the mistake, now I fixed it

[viferga]

@niko091 have you changed all line endings from:
source/loaders/rs_loader/rust/compiler/src/memory.rs ?

is that needed? can you restore it if it's not?

[niko091]

@viferga, I have reverted the changes, but I've noticed that most of the rs_loader files end with LF and some ends with CRLF.

would make sense to make them all FL? Maybe in an other PR.

[viferga]

That should go in another PR.

@niko091 We were working on this: 95e1f7f

But now is merged, we are going to review your PR and merge it today.

The linux/windows endings, we must decide one format and set it up mandatory from clang-format or even in git, so all files always have the same convention.

This should be done in another PR.
