items/union example triggers float literal compatibility lint #563
Description
The unions section has an example matching on a float literal, which triggers the rust-lang/rust#41620 compatibility lint:
#[repr(u32)]
enum Tag { I, F }
#[repr(C)]
union U {
i: i32,
f: f32,
}
#[repr(C)]
struct Value {
tag: Tag,
u: U,
}
fn is_zero(v: Value) -> bool {
unsafe {
match v {
Value { tag: I, u: U { i: 0 } } => true,
Value { tag: F, u: U { f: 0.0 } } => true,
_ => false,
}
}
}
