Struct ShapeHandle

Source

pub struct ShapeHandle<N: RealField + Copy>(/* private fields */);

Expand description

A shared handle to an abstract shape.

This can be mutated using COW.

Implementations§

Source §

impl<N: RealField + Copy> ShapeHandle<N>

Source

pub fn new<S: Shape<N>>(shape: S) -> ShapeHandle<N>

Creates a sharable shape handle from a shape.

Source

pub fn from_arc(shape: Arc<dyn Shape<N>>) -> ShapeHandle<N>

Creates a sharable shape handle from a shape trait object.

Source

pub fn as_arc(&self) -> &Arc<dyn Shape<N>>

Gets a reference the Arc refcounted shape object.

Methods from Deref<Target = dyn Shape<N>>§

Source

pub fn is<__T: Shape<N>>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

Source

pub fn downcast_rc<T: Shape<N>>(self: Rc<Self>) -> Result<Rc<T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

Source

pub fn downcast_ref<T: Shape<N>>(&self) -> Option<&T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

Source

pub fn is_shape<T: Shape<N>>(&self) -> bool

Tests if this shape has a specific type T.

Source

pub fn as_shape<T: Shape<N>>(&self) -> Option<&T>

Performs the cast.

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>

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.
