xch

A Rust library and CLI program to exchange the content of paths.

Current release: 0.1.0

Note: Currently only runs on windows or on Linux using nightly rust

CLI

The program xch can be used to eXCHange the content of two paths.

Install

cargo install xch

Usage

xch first/path second/path

After the program call, first/path will point to the previous content of second/path and vice versa. This not only works for files but also for directories or one file and a directory.

All changes are made atomically, you can never observe one change without the other (e.g. if first/path points to the old content of second/path, second/path also points to the old content of first/path).

Crate

The functionality is also available as a crate. Add xch = "0.1.0" to your Cargo.toml. Then you need to import the crate to your code

extern crate libxch;

Then you can start exchanging the content of files

if let Err(e) = libxch::xch("file1", "path/to/file2") {
    // Error handling here
}
