[−][src]Trait nphysics2d::force_generator::ForceGenerator

pub trait ForceGenerator<N: RealField, Handle: BodyHandle>: Downcast + Send + Sync {
    pub fn apply(
        &mut self, 
        parameters: &IntegrationParameters<N>, 
        bodies: &mut dyn BodySet<N, Handle = Handle>
    );
}

A persistent force generator.

A force generator applies a force to one or several bodies at each step of the simulation.

Required methods

pub fn apply(
    &mut self,
    parameters: &IntegrationParameters<N>,
    bodies: &mut dyn BodySet<N, Handle = Handle>
)[src]

Apply forces to some bodies.

Implementations

impl<N, Handle> dyn ForceGenerator<N, Handle> where
    N: Any + 'static,
    Handle: Any + 'static,
    N: RealField,
    Handle: BodyHandle, [src]

pub fn is<__T: ForceGenerator<N, Handle>>(&self) -> bool[src]

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

pub fn downcast<__T: ForceGenerator<N, Handle>>(
    self: Box<Self>
) -> Result<Box<__T>, Box<Self>>[src]

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn't.

pub fn downcast_rc<__T: ForceGenerator<N, Handle>>(
    self: Rc<Self>
) -> Result<Rc<__T>, Rc<Self>>[src]

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.

pub fn downcast_ref<__T: ForceGenerator<N, Handle>>(&self) -> Option<&__T>[src]

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

pub fn downcast_mut<__T: ForceGenerator<N, Handle>>(
    &mut self
) -> Option<&mut __T>[src]

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