Function normalize 

pub fn normalize(path: impl AsRef<Path>) -> Result<PathBuf, PathError>

Lexically normalize a path without accessing the filesystem.

Collapses ., resolves .. where possible, and removes empty segments produced by repeated separators. Leading .. components on relative paths are preserved. Absolute paths that would escape the root via .. stop at the root (Unix / or Windows drive/UNC root).

Filesystem access

No. This never calls std::fs::canonicalize and does not follow symlinks.

Drive-relative paths

Windows drive-relative paths (C:foo, C:) are rejected.

Examples

use path_rs::normalize;
use std::path::PathBuf;

let p = normalize("foo/./bar/../baz").unwrap();
assert_eq!(p, PathBuf::from("foo/baz"));
