Struct OwnedFerroPropertyChangedEventArgs 

pub struct OwnedFerroPropertyChangedEventArgs { /* private fields */ }

A property change held by value (FerroPropertyChangedEventArgs::to_owned_args): the object, the property and copies of the values in their untyped form.

This is what the handler of the PropertyChanged event of an object receives when it is attached from markup.

The priority of the binding that produced the value.

pub fn is_effective_value_change(&self) -> bool

Whether the change represents a change to the effective value of the property (as opposed to a change of a lower-priority base value).
