[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] files will be included as a benchmark target:
[INFO] [stderr] 
[INFO] [stderr] * /workspace/builds/worker-18/source/benches/nbody_uom.rs
[INFO] [stderr] * /workspace/builds/worker-18/source/benches/nbody_dimensioned.rs
[INFO] [stderr] * /workspace/builds/worker-18/source/benches/nbody_metric.rs
[INFO] [stderr] * /workspace/builds/worker-18/source/benches/nbody_raw.rs
[INFO] [stderr] 
[INFO] [stderr] This is likely to break cargo build or cargo test as these files may not be
[INFO] [stderr] ready to be compiled as a benchmark target today. You can future-proof yourself
[INFO] [stderr] and disable this warning by adding `autobenches = false` to your [package]
[INFO] [stderr] section. You may also move the files to a location where Cargo would not
[INFO] [stderr] automatically infer them to be a target, such as in subfolders.
