Function check_property_classification 

pub fn check_property_classification<T: SetObject>(
    obj: &T,
) -> Result<(), String>

Check the property classification of T against obj, a value with every field populated.

Every top-level property obj serializes MUST be in exactly one of SetObject::SERVER_SET and SetObject::CLIENT_SETTABLE, and every SetObject::IMMUTABLE name MUST be in CLIENT_SETTABLE.

Types crates call this from a test that builds obj with a struct literal and no ..Default::default(). A field added to the struct then fails to compile until the test sets it, and fails this check until it is classified.

Errors

Returns every problem found, one per line, or a single line if obj does not serialize to a JSON object.
