pub unsafe trait BoxRet: Sized {

unsafe fn box_into<'fcx>(self, fcinfo: &mut FcInfo<'fcx>) -> Datum<'fcx>;
}Expand description
Simplified variant of RetAbi.
In order to handle all of the nuances of the calling convention for returning result sets from Postgres functions, pgrx uses a very complicated trait, RetAbi. In practice, however, most types do not need to think about its many sharp-edged cases. Instead, they should implement this simplified trait, BoxRet. A blanket impl of RetAbi for BoxRet takes care of the rest.

This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
