// Issue 62307 pointed out a case where the structural-match checking
|
|
// was too shallow.
|
|
//
|
|
// Here we check similar behavior for non-empty arrays of types that
|
|
// do not derive `Eq`.
|
|
//
|
|
// (Current behavior for empty arrays differs and thus is not tested
|
|
// here; see rust-lang/rust#62336.)
