Struct FerroPropertyAccessorNode 

pub struct FerroPropertyAccessorNode { /* private fields */ }

A node that reads a registered property of an object of the class hierarchy.

Implementations

impl FerroPropertyAccessorNode

pub fn new(property: &'static FerroProperty, accepts_null: bool) -> Rc<Self>

pub fn property(&self) -> &'static FerroProperty

Trait Implementations

impl Drop for FerroPropertyAccessorNode

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ExpressionNode for FerroPropertyAccessorNode

fn state(&self) -> &NodeState

fn build_string(&self, builder: &mut String)

Appends a string representation of the node to builder.

fn on_source_changed( &self, source: Option<&BoxedValue>, _data_validation_error: Option<&BindingError>, )

Subscribes to the new source and updates the current value.

fn unsubscribe(&self, _old_source: &BoxedValue)

Unsubscribes from the previous source.

fn as_settable(&self) -> Option<&dyn ISettableNode>

fn build_string_with_nodes( &self, builder: &mut String, nodes: &[Rc<dyn ExpressionNode>], )

Builds a string representation of the binding path up to this node.

fn as_property_accessor_node(&self) -> Option<&dyn IPropertyAccessorNode>

fn as_source_node(&self) -> Option<&dyn SourceNode>

fn is_data_context_node(&self) -> bool

Whether the node reads a data context.

impl ISettableNode for FerroPropertyAccessorNode

fn value_type(&self) -> Option<ValueType>

The type of the value accepted by the node, or None if the node is not currently settable.

fn write_value_to_source( &self, value: Option<&BoxedValue>, _nodes: &[Rc<dyn ExpressionNode>], ) -> Result<bool, BindingError>

Tries to write the specified value to the source.
