Implementations§

source §

impl PolyLineLasso

source

pub fn new() -> Self

impl UnwindSafe for PolyLineLasso

Blanket Implementations§

source §

impl<T> Any for T
where T: 'static + ?Sized,

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

§

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.

§

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

§

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

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