From 1ae4ca0463d737ead1162c35b267ef5882d42883 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 13 Jun 2025 14:49:27 +0200 Subject: rust: move rust.bindgen to qemu-api crate Once qemu-api is split in multiple crates, each of them will have its own invocation of bindgen. There cannot be only one, because there are occasional "impl" blocks for the bindgen-generated structs (e.g. VMStateFlags or QOM classes) that have to reside in the same crate as the bindgen-generated code. For now, prepare for this new organization by invoking bindgen within the qemu-api crate's build definitions; it's also a much better place to list enums that need specific treatment from bindgen.
