Auto merge of #7684 - surechen:solve_derivable_impls, r=flip1995
fix for issue #7683 Fixes #7683. For Repeat [x; y] (x is the type and y is the times to repeat) . When y > 32, the compiler will report an error: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=7148558162685e91056e0550797ea74c Because https://github.com/rust-lang/rust/blob/6cdd42f9f8dd4e5e5ba0aa816bc4c99ab8b102f9/library/std/src/primitive_docs.rs#L538 /// Arrays of sizes from 0 to 32 (inclusive) implement [`Default`] trait /// if the element type allows it. As a stopgap, trait implementations are /// statically generated up to size 32. So here to detect this situation. changelog: [`derivable_impls`]: No longer lints when arrays bigger than 32 elements are involved
