defmodule VertexCacheSdk.Command do

  Behaviour for all command modules that can be executed by the VertexCache SDK.

  Implementations must define how the command is built and parsed, and return success/error
  status based on the response. This abstraction allows consistent handling of commands
  (e.g. GET, SET, DEL, PING) across the SDK.
