We use cargo vendor to generate a .cargo/config file and the vendor directory. Vendoring allows us to lock our dependencies and to modify them easily from the top level Cargo.toml. We vendor all dependencies, including the crates.io ones, which allows for network isolated builds. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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).

Usage
|
|
-----
|
|
|
|
Minimum required Rust version: 1.24.0
|
|
|
|
Add this to your `Cargo.toml`:
|
|
```toml
|
|
[dependencies]
|
|
tempfile = "3"
|
|
```
|
|
|
|
...and this to your crate root:
|
|
```rust
|
|
extern crate tempfile;
|
|
```
|
|
|
|
Example
|
|
-------
|
|
|
|
```rust
|
|
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);
|
|
}
|
|
```
