Struct sgx_tstd::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.

Methods

impl PathBuf

pub fn new() -> PathBuf

Allocates an empty PathBuf.

pub fn as_path(&self) -> &Path

Coerces to a Path slice.

pub 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.

pub fn pop(&mut self) -> bool

Truncate self to self.parent.

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

pub 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.

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.)

pub fn set_extension<S: AsRef<OsStr>>(&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.

pub fn into_os_string(self) -> OsString

Consumes the PathBuf, yielding its internal OsString storage.

Important traits for Box<I>

impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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

Converts this PathBuf into a boxed Path.

Methods from Deref<Target = Path>

pub fn as_os_str(&self) -> &OsStr

Yields the underlying OsStr slice.

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.

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.

pub fn to_path_buf(&self) -> PathBuf

Converts a Path to an owned PathBuf.

pub fn is_absolute(&self) -> bool

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.

pub fn is_relative(&self) -> bool

Return false if the Path is relative, i.e. not absolute.

See [is_absolute]'s documentation for more details.

pub fn has_root(&self) -> bool

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

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.

Important traits for Ancestors<'a>

impl<'a> Iterator for Ancestors<'a> type Item = &'a Path;

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.

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

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 ...

pub 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.

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.

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.

pub 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 .

pub 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 .

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.

pub fn with_file_name<S: AsRef<OsStr>>(&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.

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

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

See PathBuf::set_extension for more details.

Important traits for Components<'a>

impl<'a> Iterator for Components<'a> type Item = Component<'a>;

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.

• Occurentces of . are normalized away, exept 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.

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).

Important traits for Iter<'a>

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

pub fn iter(&self) -> Iter

Produces an iterator over the path's components viewed as OsStr slices.

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

pub fn display(&self) -> Display

Returns an object that implements Display for safely printing paths that may contain non-Unicode data.
