Function find_project_root 

pub fn find_project_root(start: &Path, home: Option<&Path>) -> Option<PathBuf>

Walk upward from start looking for project marker files.

home is an optional ceiling. When the walk reaches home, it stops before testing that directory for markers. This avoids accidental matches from marker files stored directly in a user’s home directory. On Windows the ceiling comparison ignores ASCII case, matching the file system.

At most MAX_WALK_DEPTH directories are tested, starting with start.

Examples

use std::path::Path;
use what_stack::find_project_root;

assert_eq!(find_project_root(Path::new("."), Some(Path::new("."))), None);
