[INFO] [stderr] warning: An explicit [[bench]] section is specified in Cargo.toml which currently
[INFO] [stderr] disables Cargo from automatically inferring other benchmark targets.
[INFO] [stderr] This inference behavior will change in the Rust 2018 edition and the following

[INFO] [stderr]

[INFO] [stderr] This is likely to break cargo build or cargo test as these files may not be
