Struct SecuredObjectSpace 

pub struct SecuredObjectSpace { /* private fields */ }

A unit of work that only does what the person signed in can do, whoever asks: a screen, an action or a call with no screen around it.

A record they cannot read is not there. A field they cannot read reads as empty, also for filters and sorting, so a filter cannot be used to guess it, and writing it back empty leaves what is stored.
