Rustup: Installing sources

[StefanoD]

Hi,
is there a possibility to install rust sources with rustup including setting the environment variable?
I need this for racer (auto completation)

Not at the moment, but this is actively being worked on:

Produce source package in rust-installer format

Make Cargo aware of standard library dependencies

And I really need this for IntelliJ Rust as well
