Type Alias nu_path::AbsolutePath

pub type AbsolutePath = Path<Absolute>;

A path that is strictly absolute.

I.e., this path is guaranteed to never be relative.

Examples

AbsolutePaths can be created by using try_absolute on a Path or by using try_new.

use nu_path::{AbsolutePath, Path};

let path1 = Path::new("/foo").try_absolute().unwrap();
let path2 = AbsolutePath::try_new("/foo").unwrap();

assert_eq!(path1, path2);

You can also use AbsolutePath::try_from or try_into. This supports attempted conversions from Path as well as types in std::path.

use nu_path::{AbsolutePath, Path};

let path1 = Path::new("/foo");
let path1: &AbsolutePath = path1.try_into().unwrap();

let path2 = std::path::Path::new("/foo");
let path2: &AbsolutePath = path2.try_into().unwrap();

assert_eq!(path1, path2)

Aliased Type

struct AbsolutePath { /* private fields */ }

Implementations

impl AbsolutePath

pub fn canonicalize(&self) -> Result<CanonicalPathBuf>

Returns the canonical, absolute form of the path with all intermediate components normalized and symbolic links resolved.

On Windows, this will also simplify to a winuser path.

This is an alias to std::fs::canonicalize.

Examples

use nu_path::{AbsolutePath, PathBuf};

let path = AbsolutePath::try_new("/foo/test/../test/bar.rs").unwrap();
assert_eq!(path.canonicalize().unwrap(), PathBuf::from("/foo/test/bar.rs"));

pub fn read_link(&self) -> Result<AbsolutePathBuf>

Reads a symbolic link, returning the file that the link points to.

This is an alias to std::fs::read_link.

Examples

use nu_path::AbsolutePath;

let path = AbsolutePath::try_new("/laputa/sky_castle.rs").unwrap();
let path_link = path.read_link().expect("read_link call failed");

pub fn try_exists(&self) -> Result<bool>

Returns Ok(true) if the path points at an existing entity.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return Ok(false).

Path::exists only checks whether or not a path was both found and readable. By contrast, try_exists will return Ok(true) or Ok(false), respectively, if the path was verified to exist or not exist. If its existence can neither be confirmed nor denied, it will propagate an Err instead. This can be the case if e.g. listing permission is denied on one of the parent directories.

Note that while this avoids some pitfalls of the exists method, it still can not prevent time-of-check to time-of-use (TOCTOU) bugs. You should only use it in scenarios where those bugs are not an issue.

Examples

use nu_path::AbsolutePath;

let path = AbsolutePath::try_new("/does_not_exist").unwrap();
assert!(!path.try_exists().unwrap());

let path = AbsolutePath::try_new("/root/secret_file.txt").unwrap();
assert!(path.try_exists().is_err());

pub fn is_symlink(&self) -> bool

Returns true if the path exists on disk and is pointing at a symbolic link.

This function will not traverse symbolic links. In case of a broken symbolic link this will also return true.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples

use nu_path::AbsolutePath;
use std::os::unix::fs::symlink;

let link_path = AbsolutePath::try_new("/link").unwrap();
symlink("/origin_does_not_exist/", link_path).unwrap();
assert_eq!(link_path.is_symlink(), true);
assert_eq!(link_path.exists(), false);

pub fn symlink_metadata(&self) -> Result<Metadata>

Queries the metadata about a file without following symlinks.

This is an alias to std::fs::symlink_metadata.

Examples

use nu_path::AbsolutePath;

let path = AbsolutePath::try_new("/Minas/tirith").unwrap();
let metadata = path.symlink_metadata().expect("symlink_metadata call failed");
println!("{:?}", metadata.file_type());
