|
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).

|
|
// Write
|
|
let mut tmpfile: File = tempfile::tempfile().unwrap();
|
|
write!(tmpfile, "Hello World!").unwrap();
|
|
|
|
// Seek to start
|
|
tmpfile.seek(SeekFrom::Start(0)).unwrap();

|
let mut buf = String::new();
