Crate uni_path

Expand description

Platform-independent path manipulation.

This module provides two types, PathBuf and Path (akin to String and str), for working with paths abstractly. These types are thin wrappers around String and str respectively, meaning that they work directly on strings.

Paths can be parsed into Components by iterating over the structure returned by the components method on Path. Components roughly correspond to the substrings between path separators (/). You can reconstruct an equivalent path from components with the push method on PathBuf; note that the paths may differ syntactically by the normalization described in the documentation for the components method.

§Simple usage

Path manipulation includes both parsing components from slices and building new owned paths.

To parse a path, you can create a Path slice from a str slice and start asking questions:

use uni_path::Path;

let path = Path::new("/tmp/foo/bar.txt");

let parent = path.parent();
assert_eq!(parent, Some(Path::new("/tmp/foo")));

let file_stem = path.file_stem();
assert_eq!(file_stem, Some("bar"));

let extension = path.extension();
assert_eq!(extension, Some("txt"));

To build or modify paths, use PathBuf:

use uni_path::PathBuf;

// This way works...
let mut path = PathBuf::from("/");

path.push("lib");
path.push("libc");

path.set_extension("so");

// ... but push is best used if you don't know everything up
// front. If you do, this way is better:
let path: PathBuf = ["/", "lib", "libc.so"].iter().collect();

Structs§

Ancestors: An iterator over Path and its ancestors.
Components: An iterator over the Components of a Path.
Iter: An iterator over the Components of a Path, as str slices.
Path: A slice of a path (akin to str).
PathBuf: An owned, mutable path (akin to String).
StripPrefixError: An error returned from Path::strip_prefix if the prefix was not found.

Enums§

Component: A single component of a path.

Constants§

MAIN_SEPARATOR: The primary separator of path components for the current platform.
