Struct PathBuf 

pub struct PathBuf { /* private fields */ }

An owned, mutable path (akin to String).

This type provides methods like push and set_extension that mutate the path in place. It also implements Deref to Path, meaning that all methods on Path slices are available on PathBuf values as well.

More details about the overall approach can be found in the crate documentation.

Examples

You can use push to build up a PathBuf from components:

use unix_path::PathBuf;

let mut path = PathBuf::new();

path.push("/");
path.push("feel");
path.push("the");

path.set_extension("force");

However, push is best used for dynamic situations. This is a better way to do this when you know all of the components ahead of time:

use unix_path::PathBuf;

let path: PathBuf = ["/", "feel", "the.force"].iter().collect();

We can still do better than this! Since these are all strings, we can use From::from:

use unix_path::PathBuf;

let path = PathBuf::from(r"/feel/the.force");

Which method works best depends on what kind of situation you’re in.

Implementations

impl PathBuf

pub fn new() -> PathBuf

Allocates an empty PathBuf.

Examples

use unix_path::PathBuf;

let path = PathBuf::new();

pub fn with_capacity(capacity: usize) -> PathBuf

Creates a new PathBuf with a given capacity used to create the internal UnixString. See with_capacity defined on UnixString.

Examples

use unix_path::PathBuf;

let mut path = PathBuf::with_capacity(10);
let capacity = path.capacity();

// This push is done without reallocating
path.push("/");

assert_eq!(capacity, path.capacity());

pub fn as_path(&self) -> &Path

Coerces to a Path slice.

Examples

use unix_path::{Path, PathBuf};

let p = PathBuf::from("/test");
assert_eq!(Path::new("/test"), p.as_path());

pub fn push<P: AsRef<Path>>(&mut self, path: P)

Extends self with path.

If path is absolute, it replaces the current path.

Examples

Pushing a relative path extends the existing path:

use unix_path::PathBuf;

let mut path = PathBuf::from("/tmp");
path.push("file.bk");
assert_eq!(path, PathBuf::from("/tmp/file.bk"));

Pushing an absolute path replaces the existing path:

use unix_path::PathBuf;

let mut path = PathBuf::from("/tmp");
path.push("/etc");
assert_eq!(path, PathBuf::from("/etc"));

pub fn pop(&mut self) -> bool

Truncates self to self.parent.

Returns false and does nothing if self.parent is None. Otherwise, returns true.

Examples

use unix_path::{Path, PathBuf};

let mut p = PathBuf::from("/test/test.rs");

p.pop();
assert_eq!(Path::new("/test"), p);
p.pop();
assert_eq!(Path::new("/"), p);

pub fn set_file_name<S: AsRef<UnixStr>>(&mut self, file_name: S)

Updates self.file_name to file_name.

If self.file_name was None, this is equivalent to pushing file_name.

Otherwise it is equivalent to calling pop and then pushing file_name. The new path will be a sibling of the original path. (That is, it will have the same parent.)

Examples

use unix_path::PathBuf;

let mut buf = PathBuf::from("/");
assert!(buf.file_name() == None);
buf.set_file_name("bar");
assert!(buf == PathBuf::from("/bar"));
assert!(buf.file_name().is_some());
buf.set_file_name("baz.txt");
assert!(buf == PathBuf::from("/baz.txt"));

pub fn set_extension<S: AsRef<UnixStr>>(&mut self, extension: S) -> bool

Updates self.extension to extension.

Returns false and does nothing if self.file_name is None, returns true and updates the extension otherwise.

If self.extension is None, the extension is added; otherwise it is replaced.

Examples

use unix_path::{Path, PathBuf};

let mut p = PathBuf::from("/feel/the");

p.set_extension("force");
assert_eq!(Path::new("/feel/the.force"), p.as_path());

p.set_extension("dark_side");
assert_eq!(Path::new("/feel/the.dark_side"), p.as_path());

pub fn into_unix_string(self) -> UnixString

Consumes the PathBuf, yielding its internal UnixString storage.

Examples

use unix_path::PathBuf;

let p = PathBuf::from("/the/head");
let bytes = p.into_unix_string();

pub fn into_boxed_path(self) -> Box<Path>

Converts this PathBuf into a boxed Path.

pub fn capacity(&self) -> usize

Invokes capacity on the underlying instance of UnixString.

pub fn clear(&mut self)

Invokes clear on the underlying instance of UnixString.

pub fn reserve(&mut self, additional: usize)

Invokes reserve on the underlying instance of UnixString.

pub fn reserve_exact(&mut self, additional: usize)

Invokes reserve_exact on the underlying instance of UnixString.

pub fn shrink_to_fit(&mut self)

Invokes shrink_to_fit on the underlying instance of UnixString.

Methods from Deref<Target = Path>

pub fn as_unix_str(&self) -> &UnixStr

Yields the underlying bytes.

Examples

use unix_path::Path;
use unix_str::UnixStr;

let os_str = Path::new("foo.txt").as_unix_str();
assert_eq!(os_str, UnixStr::new("foo.txt"));

pub fn to_str(&self) -> Option<&str>

Yields a &str slice if the Path is valid unicode.

This conversion may entail doing a check for UTF-8 validity. Note that validation is performed because non-UTF-8 strings are perfectly valid for some OS.

Examples

use unix_path::Path;

let path = Path::new("foo.txt");
assert_eq!(path.to_str(), Some("foo.txt"));

pub fn to_string_lossy(&self) -> Cow<'_, str>

Converts a Path to a Cow<str>.

Any non-Unicode sequences are replaced with U+FFFD REPLACEMENT CHARACTER.

Examples

Calling to_string_lossy on a Path with valid unicode:

use unix_path::Path;

let path = Path::new("foo.txt");
assert_eq!(path.to_string_lossy(), "foo.txt");

Had path contained invalid unicode, the to_string_lossy call might have returned "fo�.txt".

pub fn to_path_buf(&self) -> PathBuf

Converts a Path to an owned PathBuf.

Examples

use unix_path::Path;

let path_buf = Path::new("foo.txt").to_path_buf();
assert_eq!(path_buf, unix_path::PathBuf::from("foo.txt"));

pub fn is_absolute(&self) -> bool

Returns true if the Path is absolute, i.e., if it is independent of the current directory.

A path is absolute if it starts with the root, so is_absolute and has_root are equivalent.

Examples

use unix_path::Path;

assert!(!Path::new("foo.txt").is_absolute());

pub fn is_relative(&self) -> bool

Returns true if the Path is relative, i.e., not absolute.

See is_absolute’s documentation for more details.

Examples

use unix_path::Path;

assert!(Path::new("foo.txt").is_relative());

pub fn has_root(&self) -> bool

Returns true if the Path has a root.

A path has a root if it begins with /.

Examples

use unix_path::Path;

assert!(Path::new("/etc/passwd").has_root());

pub fn parent(&self) -> Option<&Path>

Returns the Path without its final component, if there is one.

Returns None if the path terminates in a root or prefix.

Examples

use unix_path::Path;

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

let grand_parent = parent.parent().unwrap();
assert_eq!(grand_parent, Path::new("/"));
assert_eq!(grand_parent.parent(), None);

pub fn ancestors(&self) -> Ancestors<'_>

Produces an iterator over Path and its ancestors.

The iterator will yield the Path that is returned if the parent method is used zero or more times. That means, the iterator will yield &self, &self.parent().unwrap(), &self.parent().unwrap().parent().unwrap() and so on. If the parent method returns None, the iterator will do likewise. The iterator will always yield at least one value, namely &self.

Examples

use unix_path::Path;

let mut ancestors = Path::new("/foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Path::new("/foo/bar")));
assert_eq!(ancestors.next(), Some(Path::new("/foo")));
assert_eq!(ancestors.next(), Some(Path::new("/")));
assert_eq!(ancestors.next(), None);

pub fn file_name(&self) -> Option<&UnixStr>

Returns the final component of the Path, if there is one.

If the path is a normal file, this is the file name. If it’s the path of a directory, this is the directory name.

Returns None if the path terminates in ...

Examples

use unix_path::Path;
use unix_str::UnixStr;

assert_eq!(Some(UnixStr::new("bin")), Path::new("/usr/bin/").file_name());
assert_eq!(Some(UnixStr::new("foo.txt")), Path::new("tmp/foo.txt").file_name());
assert_eq!(Some(UnixStr::new("foo.txt")), Path::new("foo.txt/.").file_name());
assert_eq!(Some(UnixStr::new("foo.txt")), Path::new("foo.txt/.//").file_name());
assert_eq!(None, Path::new("foo.txt/..").file_name());
assert_eq!(None, Path::new("/").file_name());

pub fn strip_prefix<P>(&self, base: P) -> Result<&Path, StripPrefixError>

where P: AsRef<Path>,

Returns a path that, when joined onto base, yields self.

Errors

If base is not a prefix of self (i.e., starts_with returns false), returns Err.

Examples

use unix_path::{Path, PathBuf};

let path = Path::new("/test/haha/foo.txt");

assert_eq!(path.strip_prefix("/"), Ok(Path::new("test/haha/foo.txt")));
assert_eq!(path.strip_prefix("/test"), Ok(Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/"), Ok(Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt"), Ok(Path::new("")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt/"), Ok(Path::new("")));
assert_eq!(path.strip_prefix("test").is_ok(), false);
assert_eq!(path.strip_prefix("/haha").is_ok(), false);

let prefix = PathBuf::from("/test/");
assert_eq!(path.strip_prefix(prefix), Ok(Path::new("haha/foo.txt")));

pub fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool

Determines whether base is a prefix of self.

Only considers whole path components to match.

Examples

use unix_path::Path;

let path = Path::new("/etc/passwd");

assert!(path.starts_with("/etc"));
assert!(path.starts_with("/etc/"));
assert!(path.starts_with("/etc/passwd"));
assert!(path.starts_with("/etc/passwd/"));

assert!(!path.starts_with("/e"));

pub fn ends_with<P: AsRef<Path>>(&self, child: P) -> bool

Determines whether child is a suffix of self.

Only considers whole path components to match.

Examples

use unix_path::Path;

let path = Path::new("/etc/passwd");

assert!(path.ends_with("passwd"));

pub fn file_stem(&self) -> Option<&UnixStr>

Extracts the stem (non-extension) portion of self.file_name.

The stem is:

• None, if there is no file name;
• The entire file name if there is no embedded .;
• The entire file name if the file name begins with . and has no other .s within;
• Otherwise, the portion of the file name before the final .

Examples

use unix_path::Path;

let path = Path::new("foo.rs");

assert_eq!("foo", path.file_stem().unwrap());

pub fn extension(&self) -> Option<&UnixStr>

Extracts the extension of self.file_name, if possible.

The extension is:

• None, if there is no file name;
• None, if there is no embedded .;
• None, if the file name begins with . and has no other .s within;
• Otherwise, the portion of the file name after the final .

Examples

use unix_path::Path;
use unix_str::UnixStr;

let path = Path::new("foo.rs");

assert_eq!(UnixStr::new("rs"), path.extension().unwrap());

pub fn join<P: AsRef<Path>>(&self, path: P) -> PathBuf

Creates an owned PathBuf with path adjoined to self.

See PathBuf::push for more details on what it means to adjoin a path.

Examples

use unix_path::{Path, PathBuf};

assert_eq!(Path::new("/etc").join("passwd"), PathBuf::from("/etc/passwd"));

pub fn with_file_name<S: AsRef<UnixStr>>(&self, file_name: S) -> PathBuf

Creates an owned PathBuf like self but with the given file name.

See PathBuf::set_file_name for more details.

Examples

use unix_path::{Path, PathBuf};

let path = Path::new("/tmp/foo.txt");
assert_eq!(path.with_file_name("bar.txt"), PathBuf::from("/tmp/bar.txt"));

let path = Path::new("/tmp");
assert_eq!(path.with_file_name("var"), PathBuf::from("/var"));

pub fn with_extension<S: AsRef<UnixStr>>(&self, extension: S) -> PathBuf

Creates an owned PathBuf like self but with the given extension.

See PathBuf::set_extension for more details.

Examples

use unix_path::{Path, PathBuf};

let path = Path::new("foo.rs");
assert_eq!(path.with_extension("txt"), PathBuf::from("foo.txt"));

pub fn components(&self) -> Components<'_>

Produces an iterator over the Components of the path.

When parsing the path, there is a small amount of normalization:

• Repeated separators are ignored, so a/b and a//b both have a and b as components.

• Occurrences of . are normalized away, except if they are at the beginning of the path. For example, a/./b, a/b/, a/b/. and a/b all have a and b as components, but ./a/b starts with an additional CurDir component.

• A trailing slash is normalized away, /a/b and /a/b/ are equivalent.

Note that no other normalization takes place; in particular, a/c and a/b/../c are distinct, to account for the possibility that b is a symbolic link (so its parent isn’t a).

Examples

use unix_path::{Path, Component};
use unix_str::UnixStr;

let mut components = Path::new("/tmp/foo.txt").components();

assert_eq!(components.next(), Some(Component::RootDir));
assert_eq!(components.next(), Some(Component::Normal(UnixStr::new("tmp"))));
assert_eq!(components.next(), Some(Component::Normal(UnixStr::new("foo.txt"))));
assert_eq!(components.next(), None)

pub fn iter(&self) -> Iter<'_>

Produces an iterator over the path’s components viewed as UnixStr slices.

For more information about the particulars of how the path is separated into components, see components.

Examples

use unix_path::{self, Path};
use unix_str::UnixStr;

let mut it = Path::new("/tmp/foo.txt").iter();
assert_eq!(it.next(), Some(UnixStr::new("/")));
assert_eq!(it.next(), Some(UnixStr::new("tmp")));
assert_eq!(it.next(), Some(UnixStr::new("foo.txt")));
assert_eq!(it.next(), None)
