Function FindAllLeftIdentityFields

expr/node.go:363–365

FindAllLeftIdentityFields Recursively descend down a node looking for all LEFT Identity Fields min(year) == {year} eq(min(user.name), max(month)) == {user, month}

(node Node)

//     eq(min(user.name), max(month)) == {user, month}

func FindAllLeftIdentityFields(node Node) []string {
	return findIdentities(node, nil).LeftStrings()
}

// FindAllIdentities gets all identity
