I am writing app that extract data from DB to array of structures.
void getSingleTrackInfo()
{
foreach(item; getTablesGPSSensorList)
{
ResultRange result = mysqlconnection.query(sqlquery);
Also I can't understand why app take so much memory? I checked
array of structures size with this code:
auto mymem = cargpspoints.length *
typeof(cargpspoints[0]).sizeof;
writeln(mymem);
And it's print: 16963440
it's about 16MB...
What is takes all other memory?

Sorry, this should be
foreach(row; result)
{
row.toStruct(cargpspoint);
arr ~= cargpspoint;
}

1. You're measuring it wrong. Array length is already measured
in terms of type size.
So should I do:
cargpspoints.length * carg
I have added GC.stat

No. .sizeof is the statically known size of a type, it can't take
into account dyn
The problem is solved. See for more detail
