| Module | Sequel::EvalInspect |
| In: |
lib/sequel/extensions/eval_inspect.rb
|
Special case objects where inspect does not generally produce input suitable for eval. Used by Sequel::SQL::Expression#inspect so that it can produce a string suitable for eval even if components of the expression have inspect methods that do not produce strings suitable for eval.
