Struct std::path::PathBuf

pub struct PathBuf {
    // some 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

fn main() { use std::path::PathBuf; let mut path = PathBuf::from("c:\\"); path.push("windows"); path.push("system32"); path.set_extension("dll"); }

use std::path::PathBuf;

let mut path = PathBuf::from("c:\\");
path.push("windows");
path.push("system32");
path.set_extension("dll");

Methods

impl PathBuf

fn new() -> PathBuf

Allocates an empty PathBuf.

fn as_path(&self) -> &Path

Coerces to a Path slice.

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

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

fn main() { use std::path::PathBuf; let mut path = PathBuf::new(); path.push("/tmp"); path.push("file.bk"); assert_eq!(path, PathBuf::from("/tmp/file.bk")); // Pushing an absolute path replaces the current path path.push("/etc/passwd"); assert_eq!(path, PathBuf::from("/etc/passwd")); }

use std::path::PathBuf;

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

// Pushing an absolute path replaces the current path
path.push("/etc/passwd");
assert_eq!(path, PathBuf::from("/etc/passwd"));

fn pop(&mut self) -> bool

Truncate self to self.parent().

Returns false and does nothing if self.file_name() is None. Otherwise, returns true.

fn set_file_name<S: AsRef<OsStr>>(&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.

Examples

fn main() { 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")); }

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"));

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

Updates self.extension() to extension.

If self.file_name() is None, does nothing and returns false.

Otherwise, returns true; if self.extension() is None, the extension is added; otherwise it is replaced.

fn into_os_string(self) -> OsString

Consumes the PathBuf, yielding its internal OsString storage.

Methods from Deref<Target=Path>

fn as_os_str(&self) -> &OsStr

Yields the underlying OsStr slice.

Examples

fn main() { use std::path::Path; let os_str = Path::new("foo.txt").as_os_str(); assert_eq!(os_str, std::ffi::OsStr::new("foo.txt")); }

use std::path::Path;

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

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.

Examples

fn main() { use std::path::Path; let path_str = Path::new("foo.txt").to_str(); assert_eq!(path_str, Some("foo.txt")); }

use std::path::Path;

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

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

fn main() { use std::path::Path; let path_str = Path::new("foo.txt").to_string_lossy(); assert_eq!(path_str, "foo.txt"); }

use std::path::Path;

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

fn to_path_buf(&self) -> PathBuf

Converts a Path to an owned PathBuf.

Examples

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

use std::path::Path;

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

fn is_absolute(&self) -> bool

A path is absolute 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. In other words, path.is_absolute() == path.prefix().is_some() && path.has_root().

Examples

fn main() { use std::path::Path; assert!(!Path::new("foo.txt").is_absolute()); }

use std::path::Path;

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

fn is_relative(&self) -> bool

A path is relative if it is not absolute.

Examples

fn main() { use std::path::Path; assert!(Path::new("foo.txt").is_relative()); }

use std::path::Path;

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

fn has_root(&self) -> bool

A path has a root if the body of the path begins with the directory separator.

• 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

fn main() { use std::path::Path; assert!(Path::new("/etc/passwd").has_root()); }

use std::path::Path;

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

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

The path without its final component, if any.

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

Examples

fn main() { 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); }

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);

fn file_name(&self) -> Option<&OsStr>

The final component of the path, if it is a normal file.

If the path terminates in ., .., or consists solely of a root of prefix, file_name will return None.

Examples

fn main() { use std::path::Path; use std::ffi::OsStr; let path = Path::new("foo.txt"); let os_str = OsStr::new("foo.txt"); assert_eq!(Some(os_str), path.file_name()); }

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

let path = Path::new("foo.txt");
let os_str = OsStr::new("foo.txt");

assert_eq!(Some(os_str), path.file_name());

fn strip_prefix<'a, P: ?Sized>(&'a self, base: &'a P) -> Result<&'a 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.

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

fn main() { use std::path::Path; let path = Path::new("/etc/passwd"); assert!(path.starts_with("/etc")); assert!(!path.starts_with("/e")); }

use std::path::Path;

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

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

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

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

fn main() { use std::path::Path; let path = Path::new("/etc/passwd"); assert!(path.ends_with("passwd")); }

use std::path::Path;

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

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

fn file_stem(&self) -> Option<&OsStr>

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

fn main() { use std::path::Path; let path = Path::new("foo.rs"); assert_eq!("foo", path.file_stem().unwrap()); }

use std::path::Path;

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

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

fn extension(&self) -> Option<&OsStr>

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

fn main() { use std::path::Path; let path = Path::new("foo.rs"); assert_eq!("rs", path.extension().unwrap()); }

use std::path::Path;

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

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

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

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

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

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));
assert_eq!(components.next(), Some(Component::Normal(OsStr::new("tmp"))));
