/// @par Equality

///

/// Instances of this class created via copy-construction or copy-assignment

/// always compare equal. Instances created with equal

/// `std::shared_ptr<*Connection>` objects compare equal. Objects that compare

/// equal share the same underlying resources.

///

/// @par Performance

///

/// Creating a new instance of this class is a relatively expensive operation,

/// new objects establish new connections to the service. In contrast,

/// copy-construction, move-construction, and the corresponding assignment

/// operations are relatively efficient as the copies share all underlying

/// resources.

///

/// @par Thread Safety

///

/// Concurrent access to different instances of this class, even if they compare

/// equal, is guaranteed to work. Two or more threads operating on the same

/// instance of this class is not guaranteed to work. Since copy-construction

/// and move-construction is a relatively efficient operation, consider using

/// such a copy when using this class from multiple threads.
