# 1.0.0[−][src]Struct std::path::PathBuf

    pub struct PathBuf { /* fields omitted */ }

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 module documentation.

# Examples

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

    use std::path::PathBuf;

    let mut path = PathBuf::new();

    path.push(r"C:\");
    path.push("windows");
    path.push("system32");

    path.set_extension("dll");

Run

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 std::path::PathBuf;

    let path: PathBuf = [r"C:\", "windows", "system32.dll"].iter().collect();

Run

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

    use std::path::PathBuf;

    let path = PathBuf::from(r"C:\windows\system32.dll");

Run

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

## Implementations

### `impl PathBuf`[src]

#### `pub fn new() -> PathBuf`[src]

Allocates an empty `PathBuf`.

# Examples

    use std::path::PathBuf;

    let path = PathBuf::new();

Run

#### `pub fn with_capacity(capacity: usize) -> PathBuf` 1.44.0[src]

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

# Examples

    use std::path::PathBuf;

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

    // This push is done without reallocating
    path.push(r"C:\");

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

Run

#### `pub fn as_path(&self) -> &Path`[src]

Coerces to a `Path` slice.

# Examples

    use std::path::{Path, PathBuf};

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

Run

#### `pub fn push<P: AsRef<Path>>(&mut self, path: P)`[src]

Extends `self` with `path`.

If `path` is absolute, it replaces the current path.

On Windows:

- if `path` has a root but no prefix (e.g., `\windows`), it replaces everything except for the prefix (if any) of `self`.
- if `path` has a prefix but no root, it replaces `self`.

# Examples

Pushing a relative path extends the existing path:

    use std::path::PathBuf;

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

Run

Pushing an absolute path replaces the existing path:

    use std::path::PathBuf;

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

Run

#### `pub fn pop(&mut self) -> bool`[src]

Truncates `self` to `self.parent`.

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

# Examples

    use std::path::{Path, PathBuf};

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

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

Run

#### `pub fn set_file_name<S: AsRef<OsStr>>(&mut self, file_name: S)`[src]

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 std::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"));

Run

#### `pub fn set_extension<S: AsRef<OsStr>>(&mut self, extension: S) -> bool`[src]

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 std::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());

Run

#### `pub fn into_os_string(self) -> OsString`[src]

Consumes the `PathBuf`, yielding its internal `OsString` storage.

# Examples

    use std::path::PathBuf;

    let p = PathBuf::from("/the/head");
    let os_str = p.into_os_string();

Run

#### `pub fn into_boxed_path(self) -> Box<Path>ⓘ

### Notable traits for Box<I>

`impl<I> Iterator for Box<I> where
I: Iterator + ?Sized, type Item = <I as Iterator>::Item;impl<F> Future for Box<F> where
F: Unpin + Future + ?Sized, type Output = <F as Future>::Output;impl<R: Read + ?Sized> Read for Box<R>impl<W: Write + ?Sized> Write for Box<W>`
`1.20.0[src]

Converts this `PathBuf` into a boxed `Path`.

#### `pub fn capacity(&self) -> usize` 1.44.0[src]

Invokes `capacity` on the underlying instance of `OsString`.

#### `pub fn clear(&mut self)`1.44.0[src]

Invokes `clear` on the underlying instance of `OsString`.

#### `pub fn reserve(&mut self, additional: usize)`1.44.0[src]

Invokes `reserve` on the underlying instance of `OsString`.

#### `pub fn reserve_exact(&mut self, additional: usize)`1.44.0[src]

Invokes `reserve_exact` on the underlying instance of `OsString`.

🔬 This is a nightly-only experimental API. (`shrink_to` #56431)

Invokes `shrink_to` on the underlying instance of `OsString`.

## Methods from Deref<Target = Path>

#### `pub fn as_os_str(&self) -> &OsStr`[src]

Yields the underlying `OsStr` slice.

# Examples

    use std::path::Path;

    let os_str = Path::new("foo.txt").as_os_str();
    assert_eq!(os_str, std::ffi::OsStr::new("foo.txt"));

Run

#### `pub fn to_str(&self) -> Option<&str>`[src]

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 std::path::Path;

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

Run

#### `pub fn to_string_lossy(&self) -> Cow<'_, str>`[src]

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 std::path::Path;

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

Run

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

#### `pub fn to_path_buf(&self) -> PathBuf`[src]

Converts a `Path` to an owned `PathBuf`.

# Examples

    use std::path::Path;

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

Run

#### `pub fn is_absolute(&self) -> bool`[src]

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

- On Unix, a path is absolute if it starts with the root, so `is_absolute` and `has_root` are equivalent.

- On Windows, a path is absolute if it has a prefix and starts with the root: `c:\windows` is absolute, while `c:temp` and `\temp` are not.

# Examples

    use std::path::Path;

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

Run

#### `pub fn is_relative(&self) -> bool`[src]

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

See `is_absolute`'s documentation for more details.

# Examples

    use std::path::Path;

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

Run

#### `pub fn has_root(&self) -> bool`[src]

Returns `true` if the `Path` has a root.

- On Unix, a path has a root if it begins with `/`.

- On Windows, a path has a root if it:

  - has no prefix and begins with a separator, e.g., `\windows`
  - has a prefix followed by a separator, e.g., `c:\windows` but not `c:windows`
  - has any non-disk prefix, e.g., `\\server\share`

# Examples

    use std::path::Path;

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

Run

#### `pub fn parent(&self) -> Option<&Path>`[src]

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

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

# Examples

    use std::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);

Run

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

### Notable traits for Ancestors<'a>

`impl<'a> Iterator for Ancestors<'a> type Item = &'a Path;`
`1.28.0[src]

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 std::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);

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

Run

#### `pub fn file_name(&self) -> Option<&OsStr>`[src]

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 std::path::Path;
    use std::ffi::OsStr;

    assert_eq!(Some(OsStr::new("bin")), Path::new("/usr/bin/").file_name());
    assert_eq!(Some(OsStr::new("foo.txt")), Path::new("tmp/foo.txt").file_name());
    assert_eq!(Some(OsStr::new("foo.txt")), Path::new("foo.txt/.").file_name());
    assert_eq!(Some(OsStr::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());

Run

#### `pub fn strip_prefix<P>(&self, base: P) -> Result<&Path, StripPrefixError> where
P: AsRef<Path>,` 1.7.0[src]

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 std::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!(path.strip_prefix("test").is_err());
    assert!(path.strip_prefix("/haha").is_err());

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

Run

#### `pub fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool`[src]

Determines whether `base` is a prefix of `self`.

Only considers whole path components to match.

# Examples

    use std::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/")); // extra slash is okay
    assert!(path.starts_with("/etc/passwd///")); // multiple extra slashes are okay

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

    assert!(!Path::new("/etc/foo.rs").starts_with("/etc/foo"));

Run

#### `pub fn ends_with<P: AsRef<Path>>(&self, child: P) -> bool`[src]

    let path = Path::new("/etc/resolv.conf");

    assert!(path.ends_with("resolv.conf"));
    assert!(path.ends_with("etc/resolv.conf"));
    assert!(path.ends_with("/etc/resolv.conf"));

    assert!(!path.ends_with("/resolv.conf"));
    assert!(!path.ends_with("conf")); // use .extension() instead

Run

#### `pub fn file_stem(&self) -> Option<&OsStr>`[src]

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 std::path::Path;

    assert_eq!("foo", Path::new("foo.rs").file_stem().unwrap());
    assert_eq!("foo.tar", Path::new("foo.tar.gz").file_stem().unwrap());

Run

#### `pub fn extension(&self) -> Option<&OsStr>`[src]

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

Run

#### `pub fn with_file_name<S: AsRef<OsStr>>(&self, file_name: S) -> PathBuf`[src]

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

See `PathBuf::set_file_name` for more details.

# Examples

    assert_eq!(path.with_extension("xz"), PathBuf::from("foo.tar.xz"));
    assert_eq!(path.with_extension("").with_extension("txt"), PathBuf::from("foo.txt"));

Run

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

### Notable traits for Components<'a>

`impl<'a> Iterator for Components<'a> type Item = Component<'a>;`
`[src]

Produces an iterator over the `Component`s 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 std::path::{Path, Component};
    use std::ffi::OsStr;

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

    assert_eq!(components.next(), Some(Component::RootDir));

### Notable traits for Iter<'a>

`impl<'a> Iterator for Iter<'a> type Item = &'a OsStr;`

Run

#### `pub fn read_dir(&self) -> Result<ReadDir>`1.5.0[src]

Returns an iterator over the entries within a directory.

The iterator will yield instances of `io::Result``<``fs::DirEntry``>`. New errors may be encountered after an iterator is initially constructed.

This is an alias to `fs::read_dir`.

# Examples

    use std::path::Path;

    let path = Path::new("/laputa");
    for entry in path.read_dir().expect("read_dir call failed") {

        }
    }

Run

#### `pub fn exists(&self) -> bool` 1.5.0[src]

Returns `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 `false`.

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

# Examples

    use std::path::Path;
    assert!(!Path::new("does_not_exist.txt").exists());

Run

# See Also

This is a convenience function that coerces errors to false. If you want to check errors, call `fs::metadata`.

#### `pub fn is_file(&self) -> bool` 1.5.0[src]

Returns `true` if the path exists on disk and is pointing at a regular file.

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

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

# Examples

    use std::path::Path;
    assert_eq!(Path::new("./is_a_directory/").is_file(), false);
    assert_eq!(Path::new("a_file.txt").is_file(), true);

Run

# See Also

This is a convenience function that coerces errors to false. If you want to check errors, call `fs::metadata` and handle its `Result`. Then call `fs::Metadata::is_file` if it was `Ok`.

When the goal is simply to read from (or write to) the source, the most reliable way to test the source can be read (or written to) is to open it. Only using `is_file` can break workflows like `diff <( prog_a )` on a Unix-like system for example. See `fs::File::open` or `fs::OpenOptions::open` for more information.

#### `pub fn is_dir(&self) -> bool` 1.5.0[src]

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

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

# Examples

    use std::path::Path;
    assert_eq!(Path::new("./is_a_directory/").is_dir(), true);
    assert_eq!(Path::new("a_file.txt").is_dir(), false);

Run

# See Also

This is a convenience function that coerces errors to false. If you want to check errors, call `fs::metadata` and handle its `Result`. Then call `fs::Metadata::is_dir` if it was `Ok`.
