A secure cross-platform temporary file library for rust. In addition to creating temporary files, this library also allows users to securely open multiple independent references to the same temporary file (useful for consumer/producer patterns and surprisingly difficult to implement securely).
extern crate tempfile;
use std::fs::File;
use std::io::{Write, Read, Seek, SeekFrom};
fn main() {
// Write
let mut tmpfile: File = tempfile::tempfile().unwrap();
write!(tmpfile, "Hello World!").unwrap();
// Seek to start
tmpfile.seek(SeekFrom::Start(0)).unwrap();
// Read
let mut buf = String::new();
tmpfile.read_to_string(&mut buf).unwrap();
assert_eq!("Hello World!", buf);
}
