• Alex (5/8) Jul 20 2017 Ok, i think i understood now.

Hi,

i don't even know if the subject makes any sense :)
What i want to achieve is: instead of making:

auto v_a = async( &load , queryA );
auto v_b = async( &load , queryB );
auto v_c = async( &load , queryC );

( async is a function from vibe and returns a "Future" - see 
http://vibed.org/api/vibe.core.concurrency/async for the async )

i want to something like this:

WHAT_TYPE[] futures;
futures ~= async( &load , queryA );
futures ~= async( &load , queryB );
futures ~= async( &load , queryC );

And then collect the results somwhere later like:

foreach(WHAT_TYPE future ; futures)
{
  writeln( future.getResult() );
}

The Problem is, i dont know what type WHAT_TYPE is / i don´t know 
how to build a loopable something of futures.

Ok, i think i understood now.

my function `load` returns `KpiResponseEntity`
so
Future!(KpiResponseEntity)[] futures;

seems to work

To get the type you can also use `typeof`.

alias ResponseType = typeof(async(&load , queryA ));
ResponseType[] futures;
futures ~= async( &load , queryA );
futures ~= async( &load , queryB );
futures ~= async( &load , queryC );
