bool	operator== (const LegalizeActionStep &RHS) const

Public Attributes
LegalizeAction	Action
	The action to take or the final answer.
unsigned	TypeIdx
	If describing an action, the type index to change. Otherwise zero.
LLT	NewType
	If describing an action, the new type for TypeIdx. Otherwise LLT{}.

Detailed Description

The result of a query.

It either indicates a final answer of Legal or Unsupported or describes an action that must be taken to make an operation more legal.
