Function is_hidden 

pub fn is_hidden(path: impl AsRef<Path>) -> Result<bool>

Returns true if the path is a hidden file or directory.

Platform-specific behavior

• On Unix, returns true if the file name starts with ..
• On Windows, returns true if the file has the hidden file attribute.

Errors

On Unix

Returns Err if any of the following are true:

• path terminates in ...
• path is not valid UTF-8.

On Windows

Returns Err if metadata about a file could not be obtained.

Examples

On Unix

assert_eq!(hf::is_hidden(".foo.txt").unwrap(), true);
assert_eq!(hf::is_hidden("foo.txt").unwrap(), false);

assert!(hf::is_hidden(".foo.txt/..").is_err());

On Windows

let temp_dir = tempfile::tempdir().unwrap();
let file_path = temp_dir.path().join("foo.txt");
assert!(!file_path.exists());

File::create(&file_path).unwrap();
assert!(file_path.exists());

// Set the hidden file attribute.
Command::new("attrib")
    .arg("+h")
    .arg(&file_path)
    .status()
    .unwrap();
assert_eq!(hf::is_hidden(&file_path).unwrap(), true);

// Clear the hidden file attribute.
Command::new("attrib")
    .arg("-h")
    .arg(&file_path)
    .status()
    .unwrap();
assert_eq!(hf::is_hidden(&file_path).unwrap(), false);

fs::remove_file(&file_path).unwrap();
assert!(hf::is_hidden(file_path).is_err());
