rust-playground

Day 1 - Install rust on Mac

Inspired by this article: http://zsiciarz.github.io/24daysofrust/index.html

Initially I had rust on brew, but it appeared not the best option due to:

• No std library source code package is attached. You'll need to download it by yourself.
• rustup is not available to mange multipe rust versions.

Hence I've uninstalled and download rustup from https://rustup.rs/

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

All rust components are installed under ~/.cargo. Ensure you have ~/.cargo/bin in PATH.

For IDE, I chose IntelliJ + Rust plugin, because I use Jetbrain's products for all other languages.
