1 error: incorrect function inside `extern` block
2 --> $DIR/issue-97193.rs:2:8
5 | ---------- `extern` blocks define existing foreign functions and functions inside of them cannot have a body
7 | ________^____________-
12 LL | | fn b(buf: &Self) {}
14 | |_____- help: remove the invalid body: `;`
16 = 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
17 = note: for more information, visit https://doc.rust-lang.org/std/keyword.extern.html
19 error: `self` parameter is only allowed in associated functions
20 --> $DIR/issue-97193.rs:2:10
22 LL | fn a(&mut self) {
23 | ^^^^^^^^^ not semantically valid as function parameter
25 = note: associated functions are those in `impl` or `trait` definitions
