[−][src]Struct path_dsl::PathDSL
A PathBuf wrapper that has support for a Path DSL.
It is usable nearly identically to a PathBuf.
Supports Deref
to
PathBuf
to cover all edge cases.
See crate documentation for usage examples.

[src]
Methods from Deref<Target = PathBuf>
pub fn as_path(&self) -> &Path
1.0.0[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());
pub fn push<P>(&mut self, path: P) where
P: AsRef<Path>,
1.0.0[src]
P: AsRef<Path>,
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) ofself
. - if
path
has a prefix but no root, it replacesself
.
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"));
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"));
pub fn pop(&mut self) -> bool
1.0.0[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("/test/test.rs"); p.pop(); assert_eq!(Path::new("/test"), p); p.pop(); assert_eq!(Path::new("/"), p);
pub fn set_file_name<S>(&mut self, file_name: S) where
S: AsRef<OsStr>,
1.0.0[src]
S: AsRef<OsStr>,
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"));
pub fn set_extension<S>(&mut self, extension: S) -> bool where
S: AsRef<OsStr>,
1.0.0[src]
S: AsRef<OsStr>,
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());
