Function walk 

pub fn walk(root: impl AsRef<Path>) -> Result<Walk>

Available on crate feature fs only.

Recursively walk root with default settings.

The defaults are:

• includes hidden files,
• does not use .gitignore or other ignore files,
• does not follow symbolic links,
• does not apply any glob include/exclude filters,
• yields files only (directory entries are skipped).

To change the configuration, use cu::fs::walker

let mut count = 0;
for entry in cu::fs::walk(".")? {
    let _entry = entry?;
    count += 1;
}
cu::info!("number of files: {count}");
