* rust: repurpose qemu_api -> testsMarc-André Lureau2025-09-171-33/+0
| | | | | | | | | | | | | | | The crate purpose is only to provide integration tests at this point, that can't easily be moved to a specific crate. It's also often a good practice to have a single integration test crate (see for ex https://github.com/rust-lang/cargo/issues/4867) Drop README.md, use docs/devel/rust.rst instead.

* rust: build: establish a baseline of lints across all cratesPaolo Bonzini2024-12-101-3/+3
| | | | | | | | | | | | | | | | Many lints that default to allow can be helpful in detecting bugs or keeping the code style homogeneous. Add them liberally, though perhaps not as liberally as in hw/char/pl011/src/lib.rs. In particular, enabling entire groups can be problematic because of bitrot when new links are added in the future. For Clippy, this is actually a feature that is only present in Cargo 1.74.0 but, since we are not using Cargo to *build* QEMU, only developers will need a new-enough cargo and only to run tools such as clippy. The requirement does not apply to distros that are building QEMU. Reviewed-by: Junjie Mao <junjie.mao@hotmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* rust: allow using build-root bindings.rs from cargoPaolo Bonzini2024-12-101-0/+29
Right now, using cargo with QEMU requires copying by hand the bindings.rs to the source tree. Instead, we can use an include file to escape the cage of cargo's mandated source directory structure. By running cargo within meson's "devenv" and adding a MESON_BUILD_ROOT environment variable, it is easy for build.rs to find the file. However, the file must be symlinked into cargo's output directory for rust-analyzer to find it. Suggested-by: Junjie Mao <junjie.mao@hotmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
