| LL | extern "C" { |
| | ---------- `extern` blocks define existing foreign functions and functions inside of them cannot have a body |
| LL | fn foo() -> i32 { |
| | ________^^^__________- |
| | | | |
| | | cannot have a body |
| LL | | return 0; |
| LL | | } |
| | |_____- help: remove the invalid body: `;` |
| | |
| = help: you might have meant to write a function accessible through FFI, which can be done by writing `extern fn` outside of the `extern` block |
