let racer locate rust sources by default
#56
Conversation
Racer looks for Rust sources by calling `rustc --print sysroot`, if `$RUST_SRC_PATH` is not set. This plays well with rustup's capability to manage rust sources along with the rest of the toolchain. To make use of this heuristic, we no longer require a source path to be explicitly configured by the user.

I apologize for not answering for so long, @Wilfred! Rustup doesn't download sources by default, since they're quite big. You need to If you scroll to the bottom, you'll find the reference to racer-rust/racer#595, with the intention of making source path discovery in racer default to rustup's location. I suppose we could call |

Done in #72. |
