Another topic of discussion at the Berlin Rust All Hands was the long-term story around Cargo, Xargo, and Rustup. The latter two tools are both involved in managing your Rust toolchain, with Xargo allowing you to build custom stds and Rustup managing pre-built artifacts for mainstream targets. Xargo is most commonly used for cross-compiling to less common platforms, but can also be used to customize the standard library on mainstream platforms.
