RndValueGen

This type will generate a Gen!T for all passed T.... Every call to genValues will call gen of all Gen structs present in values. The member values can be passed to every function accepting T....

struct RndValueGen (

T...

) {

import std.meta : staticMap;;

alias generators = T[1..$];

static if(is(typeof(T[0]) == string[]))

string[] parameterNames;

string[T.length] parameterNames;

alias Values = staticMap!(ParameterToGen, generators);
