All types in a tuple struct aren’t the same when using the #[simd]
attribute.
Erroneous code example:
#![feature(repr_simd)]
#[repr(simd)]
struct Bad(u16, u32, u32 u32); // error!When using the #[simd] attribute to automatically use SIMD operations in tuple
struct, the types in the struct must all be of the same type, or the compiler
will trigger this error.
Fixed example:
#![feature(repr_simd)]
#[repr(simd)]
struct Good(u32, u32, u32, u32); // ok!
