| error[E0259]: the name `core` is defined multiple times |

| LL | extern crate core; |
| | ^^^^^^^^^^^^^^^^^^ `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 |
| | |
| LL | extern crate core as other_core; |

| 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 |
