Method: Lotus::Utils::Kernel.inspect_type_error

Defined in:
lib/lotus/utils/kernel.rb

.inspect_type_error(arg) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns the most useful type error possible

If the object does not respond_to?(:inspect), we return the class, else we return nil. In all cases, this method is tightly bound to callers, as this method appends the required space to make the error message look good.
