[−][src]Struct abscissa_core::path::AbsPath
A reference type for a canonical filesystem path
More specifically: it is at least guaranteed to be canonical at the time it is created. There are potential TOCTTOU problems if the underlying filesystem structure changes after path canonicalization.
Methods
impl CanonicalPath
[src]
pub fn new<P>(path: &P) -> Result<&CanonicalPath, Error> where
P: AsRef<Path> + ?Sized,
[src]
P: AsRef<Path> + ?Sized,
Create a canonical path, returning error if the supplied path is not canonical
pub unsafe fn from_path_unchecked<P>(path: &P) -> &CanonicalPath where
P: AsRef<Path> + ?Sized,
[src]
P: AsRef<Path> + ?Sized,
Create a canonical path from a path, skipping the canonicalization check
This uses the same unsafe reference conversion tricks as std
to
convert from AsRef<Path>
to AsRef<CanonicalPath>
, i.e. &CanonicalPath
is a newtype for &Path
in the same way &Path
is a newtype for &OsStr
.
pub fn to_canonical_path_buf(&self) -> CanonicalPathBuf
[src]
Convert a canonical path reference into an owned CanonicalPathBuf
pub fn as_path(&self) -> &Path
[src]
Return a Path
reference.
pub fn as_os_str(&self) -> &OsStr
[src]
Return an OsStr
reference.
pub fn to_str(&self) -> Option<&str>
[src]
Yields a &str
slice if the path is valid unicode.
pub fn parent(&self) -> Result<CanonicalPathBuf, Error>
[src]
Return a canonical parent path of this path, or io::Error
if the
path is the root directory or another canonicalization error occurs.
pub fn file_name(&self) -> Option<&OsStr>
[src]
Returns the final component of the path, if there is one.
pub fn starts_with<P>(&self, base: P) -> bool where
P: AsRef<Path>,
[src]
P: AsRef<Path>,
Determines whether base is a prefix of self.
pub fn ends_with<P>(&self, child: P) -> bool where
P: AsRef<Path>,
[src]
P: AsRef<Path>,
Determines whether child is a suffix of self.
pub fn file_stem(&self) -> Option<&OsStr>
[src]
Extracts the stem (non-extension) portion of self.file_name
.
pub fn extension(&self) -> Option<&OsStr>
[src]
Extracts the extension of self.file_name
, if possible.
pub fn with_file_name<S>(&self, file_name: S) -> Result<CanonicalPathBuf, Error> where
S: AsRef<OsStr>,
[src]
S: AsRef<OsStr>,
Creates an owned CanonicalPathBuf
like self but with the given file name.
pub fn with_extension<S>(&self, extension: S) -> Result<CanonicalPathBuf, Error> where
S: AsRef<OsStr>,
[src]
S: AsRef<OsStr>,
Creates an owned CanonicalPathBuf
like self but with the given extension.
pub fn components(&self) -> Components
[src]
Produces an iterator over the Component
s of a path
pub fn iter(&self) -> Iter
[src]
Produces an iterator over the path's components viewed as
OsStr
slices.
pub fn display(&self) -> Display
[src]
Returns an object that implements Display
for safely printing
paths that may contain non-Unicode data.
pub fn metadata(&self) -> Result<Metadata, Error>
[src]
Queries the file system to get information about a file, directory, etc.
Unlike the std
version of this method, it will not follow symlinks,
since as a canonical path we should be symlink-free.
pub fn join<P>(&self, path: P) -> Result<CanonicalPathBuf, Error> where
P: AsRef<Path>,
[src]
P: AsRef<Path>,
Join a path onto a canonical path, returning a CanonicalPathBuf
.
pub fn read_dir(&self) -> Result<ReadDir, Error>
[src]
Returns an iterator over the entries within a directory.
The iterator will yield instances of io::Result
This is an alias to fs::read_dir.
pub fn exists(&self) -> bool
[src]
Does this path exist?
pub fn is_file(&self) -> bool
[src]
Is this path a file?
pub fn is_dir(&self) -> bool
[src]
Is this path a directory?
