Actually, no, that would not work. `Interlocked` operations require a stable
memory location to work on unless we use unsafe code or pinning, which
introduces complexity and potential risks.
Per ChatGPT:
## Structs and Atomic Operations
If you make your type a struct, using `Interlocked` to manipulate its
internal `Value` field directly would not work as intended for the following
reasons:
1. Copy Semantics:
- Structs are value types, so when you access or modify them, you
typically operate on a **copy**. This would break thread safety and atomicity
because each thread could be working with independent copies of the struct.
2. Interlocked Requires References:
- The `Interlocked` class operates on references to shared memory
locations. For example, `Interlocked.Exchange` and
`Interlocked.CompareExchange` require a `ref` to the field being modified.
Structs cannot provide such a reference to a field within themselves.
3. Struct Field Pinning:
- Even with unsafe code, it is challenging to guarantee safe and correct
atomic operations on a field of a struct because the struct might be moved or
copied by the runtime, breaking assumptions about its memory location.
