Features

• Makes a file in a system temporary directory
• Deletes the file on drop

  • Incomplete documentation
• temp_file_name
  • Does not delete file
  • Usage is not straightforward. Missing example.

Example

use temp_file::TempFile;
let t = TempFile::new()
  .unwrap()
  .with_contents(b"abc")
  .unwrap();
// Prints "/tmp/1a9b0".
println!("{:?}", t.path());
assert_eq!(
  "abc",
  std::fs::read_to_string(t.path()).unwrap(),
);
// Prints "/tmp/1a9b1".
println!(
    "{:?}", TempFile::new().unwrap().path());
