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).
Minimum required Rust version: 1.40.0
Add this to your Cargo.toml:
[dependencies]
tempfile = "3"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);
}
