Different file listing with different OS

[tiago-ssantos]

When executing a simple example:

use walkdir::WalkDir;

fn main() {
    for entry in WalkDir::new("./files")          
    {
        println!("{}", entry.unwrap().path().display());
    }
}

with the files:

in Windows and Ubuntu results in:

./files
./files\file1.parquet
./files\file3.parquet

but in macOs Ventura:

./files
./files/file3.parquet
./files/file1.parquet

There a specific parameter to impose a sort, but out of the box should the order by the same, independently of the OS?

should the order by the same, independently of the OS?

Certainly not. The OS determines the order. On Linux at least, the order is unspecified.

If there were some guarantee about ordering, it would definitely be in the docs. But there isn't one. You aren't even guaranteed that subsequent runs on the same OS will produce the same order.
