Is there a more compact way to describe the opCmp function in the
following struct
struct Hit
{
size_t count; // number of walkers that found this node
NWeight rank; // rank (either minimum distance or maximum
strength)
auto opCmp(const Hit rhs) const
{
if (this.count < rhs.count)
{
return -1;
}
else if (this.count > rhs.count)
{
return +1;
}
else
{
if (this.rank < rhs.rank)
{
return -1;
}
else if (this.rank > rhs.rank)
{
return +1;
}
else
{
return 0;
}
}
}
}
by reusing something like
auto opCmp(const Hit rhs) const
{
if (this.count < rhs.count)
{
return -1;
}
else if (this.count > rhs.count)
{
return +1;
}
else
{
return this.rank.standardOpCmp(rhs.rank)
}
}
