Struct React

Source

pub struct React<C: ReactComponent> { /* private fields */ }

Expand description

Component wrapper that enables reacting to component mutations.

WARNING: It is possible to remove a React from one entity and manually insert it to another entity. That WILL break the react framework. Instead use react_commands.insert(new_entity, react_component.take());.

Implementations§

Source §

impl<C: ReactComponent> React<C>

Source

pub fn get_mut<'a>( &'a mut self, rcommands: &mut ReactCommands<'_, '_>, ) -> &'a mut C

Mutably access the component and trigger reactions.

Source

pub fn get_mut_noreact(&mut self) -> &mut C

Mutably access the component without triggering reactions.

Source

pub fn take(self) -> C

Unwrap the React.

Trait Implementations§

Source §

impl<C: ReactComponent> Component for React<C>
where Self: Send + Sync + 'static,

Source §

type Storage = TableStorage

A marker type indicating the storage type used for this component. This must be either TableStorage or SparseStorage.

Source §

impl<C: ReactComponent> Deref for React<C>

Source §

type Target = C

The resulting type after dereferencing.

Source §

fn deref(&self) -> &C

Dereferences the value.

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<C> Bundle for C
where C: Component,

Source §

fn component_ids( components: &mut Components, storages: &mut Storages, ids: &mut impl FnMut(ComponentId), )

Source §

unsafe fn from_components<T, F>(ctx: &mut T, func: &mut F) -> C
where F: for<'a> FnMut(&'a mut T) -> OwningPtr<'a>,

Source §

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

Source §

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.

Source §

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.

Source §

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.

Source §

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.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

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