Add C# codegen for Clear message to reuse message objects in a pool #18782

Open batesj opened 2 weeks ago

What language does this apply to? C# codegen.

Describe the problem you are trying to solve. Using protobufs in Unity can cause excessive garbage collection overhead because of all the new class instances created while parsing a proto into a message instance.

Describe the solution you'd like I would like to be able to reuse a pool of message instances repeatedly for parsing protos.

Describe alternatives you've considered I could not find examples, but perhaps there is a way to do it with reflection? Of course, if that's expensive then it is replacing garbage with CPU overhead.

In game developing area, especially in unity, recycle message object from pool is a must-have. I'm current looking for same Clear() method like PB did for Java for recycling.
