Implementations§

Source§

impl BindingOperations

Source

pub fn do_nothing() -> BoxedValue

The marker value that tells a binding target to do nothing: the binding value is ignored.

Source

pub fn is_do_nothing(value: Option<&BoxedValue>) -> bool

Whether value is the do-nothing marker.

Source

pub fn is_unset(value: Option<&BoxedValue>) -> bool

Whether value is the unset marker.

Source

pub fn get_binding_expression_base( target: &FerroObject, property: &'static FerroProperty, ) -> Option<Rc<dyn BindingExpressionBase>>

Retrieves the binding expression that is currently active on the specified property, if any.
