Hello !
I could not find a clear way that show how to use template types
as parameter to functions:
There is a general rule to do it ? On several examples when the
return type comes from a template I saw the usage of "auto" where
the compiler will deduce the correct type but when we need to
pass that value as a parameter to a function how we declare then
as parameter ?
//void dummFunction(type<Bson,Bson,Bson> "appender",
type<forFromAuto> "another templated type")
void dummFunction(typeforFromAuto "appender", typeforFromAuto
"another templated type")
{
}
auto as = appender!string();
auto an = appender!double();
auto an = appender!customType();
auto bd = collection.find().limit(2);
struct MongoCursor(Q = Bson, R = Bson, S = Bson);
auto bd2 = collection.find(Bson(["key": Bson(3)])).limit(2);
auto bd3 = collection.find(Bson(["key": Bson(3)]), ["fld":1,
"data":1]).limit(2);
The above example is dummy example only imagine that you need to
write a function accepting one of the several templated types
returned on several parts of phobos and third party libraries
like vibed.
Can someone give a general rule for this kind of problem ?
