# Communication

### **1. Purpose**  
This module defines core enumerations and delegates used for representing the outcomes of communication operations and for implementing callback mechanisms in the DTS communication subsystem. It serves as a shared contract between communication implementations and higher-level consumers, ensuring consistent reporting of connection, disconnection, send, receive, and cancellation events across the system.

---

### **2. Public Interface**  

- **`CommunicationResult` enum**  
  A strongly-typed enumeration of possible outcomes for communication operations. Each value corresponds to a specific state or result of a communication action:  
  - `ConnectOK`, `ConnectFailed`, `ConnectTimeout` — outcomes of a connection attempt.  
  - `DisconnectOK`, `DisconnectFailed`, `DisconnectTimeout` — outcomes of a disconnection attempt.  
  - `SendOK`, `SendFailed`, `SendTimeout` — outcomes of a send operation.  
  - `ReceiveOK`, `ReceiveFailed`, `ReceiveTimeout` — outcomes of a receive operation.  
  - `Canceled` — indicates the operation was canceled (e.g., by user or timeout).  

- **`CommunicationCallback` delegate**  
  ```csharp
  public delegate bool CommunicationCallback(ICommunicationReport report);
  ```  
  A function pointer type used to register callbacks that process communication reports. It takes an `ICommunicationReport` instance as input and returns a `bool` (typically indicating whether the callback handled the report successfully or whether further processing should continue).  

---

### **3. Invariants**  
- The `CommunicationResult` enum values are exhaustive for reporting the status of communication operations; no other result codes are defined in this module.  
- Callbacks registered via `CommunicationCallback` must accept and process an `ICommunicationReport` instance; the return value semantics (e.g., `true` = handled, `false` = not handled) are implied by usage but not enforced by this module.  
- No runtime validation or normalization of enum values is performed in this module; consumers are responsible for interpreting results consistently.  

---

### **4. Dependencies**  

- **Dependencies *of* this module**:  
  - `DTS.Common.Interface.Communication.ICommunicationReport` — referenced by the `CommunicationCallback` delegate. This interface is expected to define the contract for communication reports (e.g., containing result type, timestamp, payload, etc.), but its definition is not included here.  

- **Dependencies *on* this module**:  
  - Any module implementing or consuming communication operations (e.g., network drivers, protocol handlers, UI components) is expected to reference this module to interpret operation outcomes and register callbacks.  
  - The namespace `DTS.Common.Enums.Communication` suggests this is part of a shared common library (`DTS.Common`), implying usage across multiple components in the DTS ecosystem.  

---

### **5. Gotchas**  
- **No explicit mapping between `CommunicationResult` and `ICommunicationReport` is defined here** — consumers must infer how report contents (e.g., `ICommunicationReport.Result`) correspond to `CommunicationResult` enum values.  
- **`Canceled` is a generic result** — it does not specify *which* operation was canceled (e.g., connect vs. send); callers must inspect the report context (e.g., via `ICommunicationReport.OperationType`, if defined) to disambiguate.  
- **Return value semantics of `CommunicationCallback` are not standardized in this file** — the meaning of `true`/`false` depends on the calling convention (e.g., chain-of-responsibility vs. fire-and-forget).  
- **No error codes or exception details are included** — the enum only captures high-level outcomes; detailed diagnostics must be embedded in the `ICommunicationReport` instance passed to callbacks.  

None identified beyond the above.
