C++ (Cpp) is_tuple_sub_tuple Examples

Example #1

File: subtype.c Project: pengzj/ponyc

// The subtype is a tuple, the supertype could be anything.
static bool is_tuple_subtype(ast_t* sub, ast_t* super)

  switch(ast_id(super))
  {
    case TK_NOMINAL:
      // A tuple can never be a strict subtype of a nominal type.
      return false;

    case TK_TYPEPARAMREF:
      // A tuple can never be a strict subtype of a type parameter.
      return false;

    case TK_UNIONTYPE:
      return is_subtype_union(sub, super);

    case TK_ISECTTYPE:
      return is_subtype_isect(sub, super);

    case TK_TUPLETYPE:

    case TK_ARROW:
