👎Deprecated since 0.20.0:

Use QueryBuilder instead.

Expand description

Builder struct to define the access for a FilteredResources.

This is passed to a callback in FilteredResourcesParamBuilder.

Creates a new builder with no access.

Source

pub fn access(&self) -> &Access

Returns a reference to the underlying Access.

Source

pub fn add_read_all(&mut self) -> &mut Self

Add accesses required to read all resources.

Source

pub fn add_read<R: Resource>(&mut self) -> &mut Self

Add accesses required to read the resource of the given type.

Source

pub fn add_read_by_id(&mut self, component_id: ComponentId) -> &mut Self

where T: Any,

Source §

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

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

Source §

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

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

Source §

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

Converts &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)

Converts &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> DowncastSend for T
where T: Any + Send,

Source §

fn into_any_send(self: Box<T>) -> Box<dyn Any + Send>

Converts Box<Trait> (where Trait: DowncastSend) to Box<dyn Any + Send>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.
