Struct Variable 

pub struct Variable { /* private fields */ }

Runtime property adapter used by expression scopes.

Implementations

impl Variable

pub fn new<T>(untyped_property: UntypedProperty) -> Variable

where T: PropertyValue + ToPaxValue,

Wraps an untyped property and exposes it as a PaxValue.

pub fn new_from_typed_property<T>(property: impl PropertyBinding<T>) -> Variable

where T: PropertyValue + ToPaxValue,

Wraps a typed property and exposes it as a PaxValue.

pub fn try_typed_binding<T>(&self, name: &str) -> Option<LocalProperty<T>>

where T: PropertyValue + CoercionRules,

Creates an independent one-way binding when exact typed forwarding is safe. Unlike a double binding, writes/easing on the result never mutate the source. Mismatched types and custom conversions return None.

pub fn get_untyped_property(&self) -> &UntypedProperty

pub fn get_as_pax_value(&self) -> PaxValue

Reads the current value as a PaxValue.

pub fn read_pax_value_ref<V>(&self, f: impl FnOnce(&PaxValue) -> V) -> V

Reads the current PaxValue by reference.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
