 2. (Optional) Set `RUST_SRC_PATH` environment variable to point to the 'src' dir in the Rust source installation
-   e.g. `% export RUST_SRC_PATH=/usr/local/src/rust/library` or `% export RUST_SRC_PATH="$(rustc --print sysroot)/lib/rustlib/src/rust/library"`

    It's recommended to set `RUST_SRC_PATH` for speed up, but racer detects it automatically if you don't set it.
