Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH 
environment variable. Next time you log in this will be done automatically.

To configure your current shell run source $HOME/.cargo/env
error: failed to parse manifest at `/home/zokrates/src/zokrates_field/Cargo.toml`

Caused by:
  editions are unstable

Caused by:
  feature `edition` is required

consider adding `cargo-features = ["edition"]` to the manifest
The command '/bin/sh -c curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain $RUST_TOOLCHAIN -y     && export PATH=/home/zokrates/.cargo/bin:$PATH     && (cd src;./build_release.sh)     && mv ./src/target/release/zokrates .     && mv ./src/zokrates_cli/examples .     && rustup self uninstall -y     && rm -rf $LIBSNARK_SOURCE_PATH src' returned a non-zero code: 101

The image build worked after removing edition = "2018" in zokrates_field/Cargo.toml (see kbknapp/cargo-outdated#141). I am not sure about implications of this, however, I can build the image now.

Thanks for pointing this out! We should upgrade the nightly version in Docker

Thanks. The master branch is now updated to support rust edition 2018.
I guess this can be closed?
