Function directory_exists 

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

Returns true if path exists and is a directory.

Uses std::fs::metadata (follows symlinks). Permission errors and missing paths yield false — this is a convenience wrapper, not a strict probe.

Equivalent in intent to:

path.is_dir()
    || fs::metadata(path).map(|m| m.is_dir()).unwrap_or(false)

Filesystem access

Yes. Follows symlinks. Does not populate a cache.

Prefer inspect_directory when you need error context.
