Struct WhenUiNodeListBuilder

source
pub struct WhenUiNodeListBuilder { /* private fields */ }
Expand description

Builds a node list that can be one of multiple options, selected by the first condition that is true, or a fallback default.

When the selected list changes the previous one is deinited and the new one is inited.

Implementations§

source§

impl WhenUiNodeListBuilder

source

pub fn new(default: impl UiNodeList) -> WhenUiNodeListBuilder

New with list that is used when no condition is active.

source

pub fn push(&mut self, condition: impl Var<bool>, list: impl UiNodeList)

Push a conditional list.

When condition is true and no previous inserted condition is true the list is used.

source

pub fn build(self) -> impl UiNodeList

Build a list that is always the first true condition or the default.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
