[INFO] [stderr] warning: An explicit [[example]] section is specified in Cargo.toml which currently
[INFO] [stderr] disables Cargo from automatically inferring other example targets.
[INFO] [stderr] This inference behavior will change in the Rust 2018 edition and the following
[INFO] [stderr] files will be included as a example target:
[INFO] [stderr] 
[INFO] [stderr] * /opt/crater/workdir/examples/add_remove.rs
[INFO] [stderr] * /opt/crater/workdir/examples/remove_port.rs
[INFO] [stderr] * /opt/crater/workdir/examples/add_any_port.rs
[INFO] [stderr] * /opt/crater/workdir/examples/add_port.rs
[INFO] [stderr] * /opt/crater/workdir/examples/external_ip.rs
[INFO] [stderr] * /opt/crater/workdir/examples/async.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 example target today. You can future-proof yourself
[INFO] [stderr] and disable this warning by adding `autoexamples = 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.
