Download Rust Sources manually

If for some reason you need to download the rust sources manually just follow this simple procedure.

• Download the source tar file from https://www.rust-lang.org/en-US/downloads.html for your version (alternatively you can browse the Downloads Archive from the official Rust site).
• Go to your Sublime Text 3 Packages directory (you can open it using Preferences -> Browse Packages in your ST3 menu bar)
• Extract the tar file into Packages/anaconda_rust
• Rename the extracted folder to the version that your get with rustc -V (just the version, without the rustc word or the commit hash if any), for example 1.12.0-nightly.
• Call it a day
