The temporary file will have been deleted. You should be
able to reproduce the same output from racer with the
following command:

$ CARGO_HOME=/home/evgeniy/.cargo RUST_SRC_PATH=/home/evgeniy/.rustup/toolchains/beta-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src /home/evgeniy/.cargo/bin/racer find-definition 365 29 /home/evgeniy/.cargo/registry/src/github.com-1ecc6299db9ec823/syntex_syntax-0.58.1/src/print/pprust.rs
