I remember that there was topic about remobing data from
struct/arrays of structs. But I do not remember what is
idiomatic way to do it, and can't google it.
something like:
struct MyTrack
{
ulong id;
string recordDate;
int velocity;
int maxAllowedSpeedForRoad;
}
MyTrack mytrack;
MyTrack [] mytracks;
// filling
mytracks.clean() or what?
There are multiple options
// Will set the array to an empty one, and leave the
// old one for the GC to clean up when it feels like it.
// The safest way.
mytracks = null;
// Mostly equivalent:
mytracks = [];
// Will reuse the array, overwriting existing data.
// If other parts of the program are using existing data
// in the array, this will lead to hard-to-track-down bugs.
mytracks.length = 0;
mytracks.assumeSafeAppend();
// If you just want to get rid of the last element you added to
the array:
mytracks = mytracks[0..$-1];
