Trait nphysics3d::force_generator::ForceGenerator [−][src]
pub trait ForceGenerator<N: RealField + Copy, Handle: BodyHandle>: Downcast + Send + Sync { fn apply(
&mut self,
parameters: &IntegrationParameters<N>,
bodies: &mut dyn BodySet<N, Handle = Handle>
); }
Expand description
A persistent force generator.
A force generator applies a force to one or several bodies at each step of the simulation.
Required methods
fn apply(
&mut self,
parameters: &IntegrationParameters<N>,
bodies: &mut dyn BodySet<N, Handle = Handle>
)
fn apply(
&mut self,
parameters: &IntegrationParameters<N>,
bodies: &mut dyn BodySet<N, Handle = Handle>
)
Apply forces to some bodies.
Implementations
impl<N, Handle> dyn ForceGenerator<N, Handle> where
N: Any + 'static,
Handle: Any + 'static,
N: RealField + Copy,
Handle: BodyHandle,
impl<N, Handle> dyn ForceGenerator<N, Handle> where

Returns true if the trait object wraps an object of type __T
.
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>>
pub fn downcast_rc<__T: ForceGenerator<N, Handle>>(
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.
Returns a reference to the object within the trait object if it is of type __T
, or
None
if it isn’t.
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn’t.
