Struct typed_path::Utf8PathBuf

pub struct Utf8PathBuf<T>where
    T: for<'enc> Utf8Encoding<'enc>,{ /* private fields */ }

An owned, mutable path that mirrors std::path::PathBuf, but operatings using a Utf8Encoding to determine how to parse the underlying str.

This type provides methods like push and set_extension that mutate the path in place. It also implements Deref to Utf8Path, meaning that all methods on Utf8Path slices are available on Utf8PathBuf values as well.

Examples

You can use push to build up a Utf8PathBuf from components:

use typed_path::{Utf8PathBuf, Utf8WindowsEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut path = Utf8PathBuf::<Utf8WindowsEncoding>::new();

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

path.set_extension("dll");

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 typed_path::{Utf8PathBuf, Utf8WindowsEncoding};

let path: Utf8PathBuf<Utf8WindowsEncoding> = [
    r"C:\",
    "windows",
    "system32.dll",
].iter().collect();

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

use typed_path::{Utf8PathBuf, Utf8WindowsEncoding};

let path = Utf8PathBuf::<Utf8WindowsEncoding>::from(r"C:\windows\system32.dll");

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

Implementations

impl<T> Utf8PathBuf<T>where
    T: for<'enc> Utf8Encoding<'enc>,

pub fn new() -> Self

Allocates an empty Utf8PathBuf.

Examples

use typed_path::{Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let path = Utf8PathBuf::<Utf8UnixEncoding>::new();

pub fn with_capacity(capacity: usize) -> Self

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

Examples

use typed_path::{Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut path = Utf8PathBuf::<Utf8UnixEncoding>::with_capacity(10);
let capacity = path.capacity();

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

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

pub fn as_path(&self) -> &Utf8Path<T>

Coerces to a Utf8Path slice.

Examples

use typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let p = Utf8PathBuf::<Utf8UnixEncoding>::from("/test");
assert_eq!(Utf8Path::new("/test"), p.as_path());

pub fn push<P: AsRef<Utf8Path<T>>>(&mut self, path: P)

Extends self with path.

If path is absolute, it replaces the current path.

With Utf8WindowsPathBuf:

• 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.
• if self has a verbatim prefix (e.g. \\?\C:\windows) and path is not empty, the new path is normalized: all references to . and .. are removed.

Examples

Pushing a relative path extends the existing path:

use typed_path::{Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut path = Utf8PathBuf::<Utf8UnixEncoding>::from("/tmp");
path.push("file.bk");
assert_eq!(path, Utf8PathBuf::from("/tmp/file.bk"));

Pushing an absolute path replaces the existing path:

use typed_path::{Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut path = Utf8PathBuf::<Utf8UnixEncoding>::from("/tmp");
path.push("/etc");
assert_eq!(path, Utf8PathBuf::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 typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut p = Utf8PathBuf::<Utf8UnixEncoding>::from("/spirited/away.rs");

p.pop();
assert_eq!(Utf8Path::new("/spirited"), p);
p.pop();
assert_eq!(Utf8Path::new("/"), p);

pub fn set_file_name<S: AsRef<str>>(&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 typed_path::{Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A pathbuf cannot be created on its own without a defined encoding
let mut buf = Utf8PathBuf::<Utf8UnixEncoding>::from("/");
assert!(buf.file_name() == None);
buf.set_file_name("bar");
assert!(buf == Utf8PathBuf::from("/bar"));
assert!(buf.file_name().is_some());
buf.set_file_name("baz.txt");
assert!(buf == Utf8PathBuf::from("/baz.txt"));

pub fn set_extension<S: AsRef<str>>(&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 typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

let mut p = Utf8PathBuf::<Utf8UnixEncoding>::from("/feel/the");

p.set_extension("force");
assert_eq!(Utf8Path::new("/feel/the.force"), p.as_path());

p.set_extension("dark_side");
assert_eq!(Utf8Path::new("/feel/the.dark_side"), p.as_path());

pub fn into_string(self) -> String

Consumes the PathBuf, yielding its internal String storage.

Examples

use typed_path::{Utf8PathBuf, Utf8UnixEncoding};

let p = Utf8PathBuf::<Utf8UnixEncoding>::from("/the/head");
let s = p.into_string();

Consumes PathBuf and returns a new Utf8PathBuf by checking that the path contains valid UTF-8.

Errors

Returns Err if the path is not UTF-8 with a description as to why the provided component is not UTF-8.

Examples

use typed_path::{PathBuf, Utf8PathBuf, UnixEncoding, Utf8UnixEncoding};

let path_buf = PathBuf::<UnixEncoding>::from(&[0xf0, 0x9f, 0x92, 0x96]);
let utf8_path_buf = Utf8PathBuf::<Utf8UnixEncoding>::from_bytes_path_buf(path_buf).unwrap();
assert_eq!(utf8_path_buf.as_str(), "💖");

pub unsafe fn from_bytes_path_buf_unchecked<U>(path_buf: PathBuf<U>) -> Selfwhere
    U: for<'enc> Encoding<'enc>,

Consumes PathBuf and returns a new Utf8PathBuf by checking that the path contains valid UTF-8.

Errors

Returns Err if the path is not UTF-8 with a description as to why the provided component is not UTF-8.

Safety

Examples

use typed_path::{PathBuf, Utf8PathBuf, UnixEncoding, Utf8UnixEncoding};

let path_buf = PathBuf::<UnixEncoding>::from(&[0xf0, 0x9f, 0x92, 0x96]);
let utf8_path_buf = unsafe {
    Utf8PathBuf::<Utf8UnixEncoding>::from_bytes_path_buf_unchecked(path_buf)
};
assert_eq!(utf8_path_buf.as_str(), "💖");

pub fn into_bytes_path_buf<U>(self) -> PathBuf<U>where
    U: for<'enc> Encoding<'enc>,

Consumes Utf8PathBuf and returns a new PathBuf

Examples

use typed_path::{PathBuf, Utf8PathBuf, UnixEncoding, Utf8UnixEncoding};

let utf8_path_buf = Utf8PathBuf::<Utf8UnixEncoding>::from("💖");
let path_buf = utf8_path_buf.into_bytes_path_buf::<UnixEncoding>();
assert_eq!(path_buf.as_bytes(), &[0xf0, 0x9f, 0x92, 0x96]);

Methods from Deref<Target = Utf8Path<T>>

pub fn as_str(&self) -> &str

Yields the underlying str slice.

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let s = Utf8Path::<Utf8UnixEncoding>::new("foo.txt").as_str();
assert_eq!(s, "foo.txt");

pub fn to_path_buf(&self) -> Utf8PathBuf<T>

Converts a Utf8Path to an owned Utf8PathBuf.

Examples

use typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path_buf = Utf8Path::<Utf8UnixEncoding>::new("foo.txt").to_path_buf();
assert_eq!(path_buf, Utf8PathBuf::from("foo.txt"));

pub fn is_absolute(&self) -> bool

Returns true if the Utf8Path is absolute, i.e., if it is independent of the current directory.

• On Unix (Utf8UnixPath]), a path is absolute if it starts with the root, so is_absolute and has_root are equivalent.

• On Windows (Utf8WindowsPath), 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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert!(!Utf8Path::<Utf8UnixEncoding>::new("foo.txt").is_absolute());

pub fn is_relative(&self) -> bool

Returns true if the Utf8Path is relative, i.e., not absolute.

See is_absolute’s documentation for more details.

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert!(Utf8Path::<Utf8UnixEncoding>::new("foo.txt").is_relative());

pub fn has_root(&self) -> bool

Returns true if the Utf8Path has a root.

• On Unix (Utf8UnixPath), a path has a root if it begins with /.

• On Windows (Utf8WindowsPath), 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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert!(Utf8Path::<Utf8UnixEncoding>::new("/etc/passwd").has_root());

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

Returns the Utf8Path without its final component, if there is one.

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

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("/foo/bar");
let parent = path.parent().unwrap();
assert_eq!(parent, Utf8Path::new("/foo"));

let grand_parent = parent.parent().unwrap();
assert_eq!(grand_parent, Utf8Path::new("/"));
assert_eq!(grand_parent.parent(), None);

pub fn ancestors(&self) -> Utf8Ancestors<'_, T>

Produces an iterator over Utf8Path and its ancestors.

The iterator will yield the Utf8Path 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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let mut ancestors = Utf8Path::<Utf8UnixEncoding>::new("/foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Utf8Path::new("/foo/bar")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("/foo")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("/")));
assert_eq!(ancestors.next(), None);

// NOTE: A path cannot be created on its own without a defined encoding
let mut ancestors = Utf8Path::<Utf8UnixEncoding>::new("../foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Utf8Path::new("../foo/bar")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("../foo")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("..")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("")));
assert_eq!(ancestors.next(), None);

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

Returns the final component of the Utf8Path, 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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert_eq!(Some("bin"), Utf8Path::<Utf8UnixEncoding>::new("/usr/bin/").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::<Utf8UnixEncoding>::new("tmp/foo.txt").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::<Utf8UnixEncoding>::new("foo.txt/.").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::<Utf8UnixEncoding>::new("foo.txt/.//").file_name());
assert_eq!(None, Utf8Path::<Utf8UnixEncoding>::new("foo.txt/..").file_name());
assert_eq!(None, Utf8Path::<Utf8UnixEncoding>::new("/").file_name());

pub fn strip_prefix<P>(&self, base: P) -> Result<&Utf8Path<T>, StripPrefixError>where
    P: AsRef<Utf8Path<T>>,

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 typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("/test/haha/foo.txt");

assert_eq!(path.strip_prefix("/"), Ok(Utf8Path::new("test/haha/foo.txt")));
assert_eq!(path.strip_prefix("/test"), Ok(Utf8Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/"), Ok(Utf8Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt"), Ok(Utf8Path::new("")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt/"), Ok(Utf8Path::new("")));

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

let prefix = Utf8PathBuf::<Utf8UnixEncoding>::from("/test/");
assert_eq!(path.strip_prefix(prefix), Ok(Utf8Path::new("haha/foo.txt")));

pub fn starts_with<P>(&self, base: P) -> boolwhere
    P: AsRef<Utf8Path<T>>,

Only considers whole path components to match.

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::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!(!Utf8Path::<Utf8UnixEncoding>::new("/etc/foo.rs").starts_with("/etc/foo"));

pub fn ends_with<P>(&self, child: P) -> boolwhere
    P: AsRef<Utf8Path<T>>,

Determines whether child is a suffix of self.

Only considers whole path components to match.

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::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

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

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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert_eq!("foo", Utf8Path::<Utf8UnixEncoding>::new("foo.rs").file_stem().unwrap());
assert_eq!("foo.tar", Utf8Path::<Utf8UnixEncoding>::new("foo.tar.gz").file_stem().unwrap());

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

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 typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert_eq!("rs", Utf8Path::<Utf8UnixEncoding>::new("foo.rs").extension().unwrap());
assert_eq!("gz", Utf8Path::<Utf8UnixEncoding>::new("foo.tar.gz").extension().unwrap());

pub fn join<P: AsRef<Utf8Path<T>>>(&self, path: P) -> Utf8PathBuf<T>

Creates an owned Utf8PathBuf with path adjoined to self.

See Utf8PathBuf::push for more details on what it means to adjoin a path.

Examples

use typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
assert_eq!(
    Utf8Path::<Utf8UnixEncoding>::new("/etc").join("passwd"),
    Utf8PathBuf::from("/etc/passwd"),
);

pub fn with_file_name<S: AsRef<str>>(&self, file_name: S) -> Utf8PathBuf<T>

Creates an owned Utf8PathBuf like self but with the given file name.

See Utf8PathBuf::set_file_name for more details.

Examples

use typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("/tmp/foo.txt");
assert_eq!(path.with_file_name("bar.txt"), Utf8PathBuf::from("/tmp/bar.txt"));

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("/tmp");
assert_eq!(path.with_file_name("var"), Utf8PathBuf::from("/var"));

pub fn with_extension<S: AsRef<str>>(&self, extension: S) -> Utf8PathBuf<T>

Creates an owned Utf8PathBuf like self but with the given extension.

See Utf8PathBuf::set_extension for more details.

Examples

use typed_path::{Utf8Path, Utf8PathBuf, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("foo.rs");
assert_eq!(path.with_extension("txt"), Utf8PathBuf::from("foo.txt"));

// NOTE: A path cannot be created on its own without a defined encoding
let path = Utf8Path::<Utf8UnixEncoding>::new("foo.tar.gz");
assert_eq!(path.with_extension(""), Utf8PathBuf::from("foo.tar"));
assert_eq!(path.with_extension("xz"), Utf8PathBuf::from("foo.tar.xz"));
assert_eq!(path.with_extension("").with_extension("txt"), Utf8PathBuf::from("foo.txt"));

pub fn components(&self) -> <T as Utf8Encoding<'_>>::Components

Produces an iterator over the Utf8Components 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 typed_path::{Utf8Path, Utf8UnixEncoding, unix::Utf8UnixComponent};

// NOTE: A path cannot be created on its own without a defined encoding
let mut components = Utf8Path::<Utf8UnixEncoding>::new("/tmp/foo.txt").components();

assert_eq!(components.next(), Some(Utf8UnixComponent::RootDir));
assert_eq!(components.next(), Some(Utf8UnixComponent::Normal("tmp")));
assert_eq!(components.next(), Some(Utf8UnixComponent::Normal("foo.txt")));
assert_eq!(components.next(), None)

pub fn iter(&self) -> Utf8Iter<'_, T>

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

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

Examples

use typed_path::{Utf8Path, Utf8UnixEncoding};

// NOTE: A path cannot be created on its own without a defined encoding
let mut it = Utf8Path::<Utf8UnixEncoding>::new("/tmp/foo.txt").iter();

assert_eq!(it.next(), Some(typed_path::unix::SEPARATOR_STR));
assert_eq!(it.next(), Some("tmp"));
assert_eq!(it.next(), Some("foo.txt"));
assert_eq!(it.next(), None)

pub fn as_bytes_path<U>(&self) -> &Path<U>where
