A Rust library for creating a temporary directory and deleting its entire contents when the directory is dropped.
Add this to your Cargo.toml
:
[dependencies]
tempdir = "0.3"
and this to your crate root:
extern crate tempdir;
This sample method does the following:
- Create a temporary directory in the default location with the given prefix.
- Determine a file path in the directory and print it out.
- Create a file inside the temp folder.
- Write to the file and sync it to disk.
- Close the directory, deleting the contents in the process.
fn write_temp_folder_with_files() -> Result<(), io::Error> {
if let Ok(dir) = TempDir::new("my_directory_prefix") {
let file_path = dir.path().join("foo.txt");
println!("{:?}", file_path);
let mut f = try!(File::create(file_path));
try!(f.write_all(b"Hello, world!"));
try!(f.sync_all());
try!(dir.close());
}
Ok(())
}
Note: Closing the directory is actually optional, as it would be done on drop. The benefit of closing here is that it allows possible errors to be handled.
