// RUN: mlir-opt %s -test-elements-attr-interface -verify-diagnostics

// This test contains various `ElementsAttr` attributes, and tests the support
// for iterating the values of these attributes using various native C++ types.
// This tests that the abstract iteration of ElementsAttr works properly, and
// is properly failable when necessary.
