structs | Utilities for Go structs

Any Ideas why the IOCP is not passing the Completion Key?

of course it passing back exactly what you pass to CreateIoCompletionPort and I/O in place pointer to OVERLAPPED

but at first

You can write a trait like this:

If the memory pool was allocated as a single object (like result of a single malloc() or a global array) then pointer arithmetics can be safely used.

Implemented custom unmarshler for config type.

Note

• If you don't need Parameters and dynamicParametes as struct types, you can simply unmarshal them into map[string]string

• you have to expose all fields in your structs to do json unmarshaling

• validate your json string

Perhaps you missed it: Eric Lippert has mentioned it in a side note:

[...] and static variables are stored on the heap.

That's written in the context of

The truth is that this is an implementation detail [...]

Here's how the Microsoft implementation does it:

But why are static variables stored on the heap?

Well, even the Main() method does not live forever. The Main() method could end and some other threads could still be running. What should happen in such a case to the struct? It needn't necessarily be on the heap, but I hope you see that it can't be on the stack and not in a register. The struct must be somewhere for other threads to still be able to access it. Heaps are a good choice.

Code example where Main() dies:

This may be a packing issue. Consider using Unity's Color32 struct, which is perfectly aligned for use in native code.

Also you can't pass managed array as ref (because ref may also add internal info, such as array length before actual data, which become overwritten by DLL code), for this call you should use

Your issue is immediately solved if ProposedChange is a struct and not a class. Unless its instances have their own life cycle, then they are just holders of value, so should be semantically a struct.

The reason your issue is solved is because mutating a property of a struct mutates the struct, so SwiftUI knows to recompute the view, whereas with a class you need to subscribe to changes.

Assuming ProposedChange is a struct:

You can extract a base struct which has field DateLastModified time.Time and methods like isBefore(start), isAfter(end), isBetween(start, end)

The problem is that there is a missing : after office, just like the error message is saying.

There is also another : missing after workstationNo.

Try struct,workstationNo: int>.
