This Week in Cargo

Cargo is the Mozilla-funded package manager slash build tool for Rust code. Cargo is being developed by Tilde, in part due to their previous experience building Bundler. You can find Cargo's website at http://crates.io/. Apparently, a startup is already using cargo.io. Darn! The source of the website is here currently, if you'd like to add or change anything.

Cargo had its first 'release' on Monday, so this is the very first TWiC! As part of this, Cargo has moved to the rust-lang organization. That commit also serves as the original release. Cargo is 'pre-alpha,' so no actual releases have been tagged. Yet. Basically, Cargo is at a point where it is able to be used for basic Rust projects, and dogfooding it will help make it awesome.

Uptake has been pretty good: A search on GitHub shows a large number of code that references Cargo. Of course, some people will still use other projects to handle this, especially with Cargo's lack of features.

For a short introduction to Cargo, see my section in the new Guide. One note that's not in there, however: you're intended to check your Cargo.toml file into version control, similarly to a Makefile.
