Detailed Description

template<typename... Rules>
class arg_router::policy::validation::validator< Rules >

A policy that provides validation checking against a parse tree root.

The rules are checked in order, so where there is overlap (i.e. a policy or tree_node could be valid in multiple entries) be sure to list the more specific rule first.
