This is a new lint introduced in Rust 1.88. It does not affect
compilation when using a previous version or our MSRV, 1.77. But with
1.88 compilation fails because we deny all warnings:
error: unnecessary transmute
--> rust/qemu-api/libqemu_api.rlib.p/structured/bindings.inc.rs:729:18
|
729 | unsafe { ::std::mem::transmute(self._bitfield_1.get(0usize, 24u8) as u32) }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace this with: `u32::cast_signed(self._bitfield_1.get(0usize, 24u8) as u32)`
|
= note: `-D unnecessary-transmutes` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unnecessary_transmutes)]`
Allow this lint, which even though it does not exist in previous
versions, it works because we allow for `unknown_lints` in
rust/Cargo.toml.
