| | ^^^^^^^^^^^^^^^^^^ `core` reimported here | |
| | | |
| = note: `core` must be defined only once in the type namespace of this module | |
| help: you can use `as` to change the binding name of the import | |

| error: `#[panic_handler]` function required, but not found | |
| error: unwinding panics are not supported without std | |
| | | |
| = help: using nightly cargo, use -Zbuild-std with panic="abort" to avoid unwinding | |
| = note: since the core library is usually precompiled with panic="unwind", rebuilding your crate with panic="abort" may not be enough to fix the problem | |
| error: aborting due to 3 previous errors | |
