The compiler team's explanation
Note: this error code is no longer emitted by the compiler.
When using the #[simd] attribute on a tuple struct, the components of the tuple struct must all be of a concrete, nongeneric type so the compiler can reason about how to use SIMD with them. This error will occur if the types are generic.
This will cause an error:
#![feature(repr_simd)]
#[repr(simd)]
struct Bad<T>([T; 4]);This will not:
#![feature(repr_simd)]
#[repr(simd)]
struct Good([u32; 4]);From rustc --explain E0074 (1.99.0), part of the Rust project, MIT or Apache-2.0. Official page.
