Understanding "Zero Allocation" #652

Closed CaledoniaProject closed 6 months ago

CaledoniaProject commented 6 months ago

Hi there, I'm wondering what "Zero Allocation" means? If you're talking about "No data copy", I'm wondering how it's implemented.

It means that the average amount of allocation on heap is zero, which is expensive because it has to be garbage collected. It still allocates on stack, but allocating and freeing on stack is cheaper.
