Struct tmp_env::TmpDir

pub struct TmpDir(_);

A helper datastructure for ensuring that we delete the tmp dir created before end of the current scope.

Methods from Deref<Target = PathBuf>

pub fn as_path(&self) -> &Path

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>, 

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

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

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("/spirited/away.rs");

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

pub fn set_file_name<S>(&mut self, file_name: S) where
    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>, 

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());

pub fn capacity(&self) -> usize

Invokes capacity on the underlying instance of OsString.

pub fn clear(&mut self)

Invokes clear on the underlying instance of OsString.

pub fn reserve(&mut self, additional: usize)

Invokes reserve on the underlying instance of OsString.

pub fn reserve_exact(&mut self, additional: usize)

Invokes reserve_exact on the underlying instance of OsString.

pub fn shrink_to_fit(&mut self)

Invokes shrink_to_fit on the underlying instance of OsString.

pub fn shrink_to(&mut self, min_capacity: usize)

🔬 This is a nightly-only experimental API. (shrink_to)

Invokes shrink_to on the underlying instance of OsString.
