// TODO: Add AST tests for RasterizerOrderedBuffer here
// This test tests two different AST generations each typed buffer.
// The "EMPTY" test mode verifies the AST generated by forward declaration
// of the HLSL types which happens on initializing the HLSL external AST with
// an AST Context.
// The non-empty mode has a use that requires the resource type be complete,
// which results in the AST being populated by the external AST source. That
// case covers the full implementation of the template declaration and the
// instantiated specialization.
