FSharedStruct | Unreal Engine 5.8 Documentation

API > API/Runtime > API/Runtime/CoreUObject

FSharedStruct works similarly as a TSharedPtr but avoids the double pointer indirection. (One pointer for the FInstancedStruct and one pointer for the struct memory it is wrapping). Also note that because of its implementation, it is not possible for now to go from a struct reference or struct view back to a shared struct.

This struct type is also convertible to a FStructView / FConstStructView, and like FInstancedStruct, it is the preferable way of passing it as a parameter. If the calling code would like to keep a shared pointer to the struct, you may pass the FSharedStruct as a parameter, but it is recommended to pass it as a "const FSharedStruct&" to limit the unnecessary recounting.

A 'const FSharedStruct' cannot be made to point at another instance of a struct, whilst a vanilla FSharedStruct can. In either case, the shared struct memory /data is mutable.
