error: incorrect function inside `extern` block

LL | extern "C" {
| ---------- `extern` blocks define existing foreign functions and functions inside of them cannot have a body
LL | fn foo() -> i32 {
| ________^^^__________-

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
