camino-tempfile

A secure, cross-platform, temporary file library for Rust with UTF-8 paths.

This crate is a wrapper around tempfile that works with the Utf8Path and Utf8PathBuf types defined by camino. If your code mostly uses camino, it can be annoying to have to convert temporary paths to Utf8Path over and over again. This crate manages that for you.

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).

This crate closely mirrors tempfile's interface. For extensions that provide quality-of-life improvements such as the ability to create files easily, see camino-tempfile-ext.

Usage

Add this to your Cargo.toml:

camino-tempfile = "1"

Example

use std::fs::File;
use std::io::{Write, Read, Seek, SeekFrom};

fn main() {
    // Write
    let mut tmpfile: File = camino_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);
}

Minimum supported Rust version (MSRV)
