[INFO] [stderr] warning: An explicit [[bin]] section is specified in Cargo.toml which currently
[INFO] [stderr] disables Cargo from automatically inferring other binary targets.
[INFO] [stderr] This inference behavior will change in the Rust 2018 edition and the following
[INFO] [stderr] files will be included as a binary target:
[INFO] [stderr] 
[INFO] [stderr] * /workspace/builds/worker-6/source/src/bin/config.rs

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

[INFO] [stderr] and disable this warning by adding `autobins = false` to your [package]
