Struct DefaultBodySet 

pub struct DefaultBodySet<N>
where
    N: RealField + Copy,
{ /* private fields */ }

The default set containing all the bodies added to the world.

It is based on an arena using generational indices to avoid the ABA problem.

Implementations

impl<N> DefaultBodySet<N>

where N: RealField + Copy,

pub fn new() -> DefaultBodySet<N>

Creates an empty set.

pub fn insert(&mut self, body: impl Body<N>) -> Index

Adds a body to this set.

pub fn insert_boxed(&mut self, body: Box<dyn Body<N>>) -> Index

Adds a body (represented as a boxed trait-object) to this set.

pub fn remove(&mut self, to_remove: Index) -> Option<Box<dyn Body<N>>>

Removes a body from this set.

pub fn get(&self, handle: Index) -> Option<&(dyn Body<N> + 'static)>

Gets a reference to the body identified by handle.

pub fn get_mut(&mut self, handle: Index) -> Option<&mut (dyn Body<N> + 'static)>

Gets a mutable reference to the body identified by handle.

pub fn iter(&self) -> impl Iterator<Item = (Index, &(dyn Body<N> + 'static))>

Iterate through all the bodies and their handles.

pub fn iter_mut( &mut self, ) -> impl Iterator<Item = (Index, &mut (dyn Body<N> + 'static))>

Mutably iterate through all the bodies and their handles.

pub fn rigid_body(&self, handle: Index) -> Option<&RigidBody<N>>

Gets the rigid body identified by handle.

Returns None if the body does not exists, of if it exists but is not a rigid body.

pub fn rigid_body_mut(&mut self, handle: Index) -> Option<&mut RigidBody<N>>

Gets a mutable reference to the rigid body identified by handle.

Returns None if the body does not exists, of if it exists but is not a rigid body.

pub fn multibody(&self, handle: Index) -> Option<&Multibody<N>>

Gets the multibody identified by handle.

Returns None if the body does not exists, of if it exists but is not a multibody.

pub fn multibody_mut(&mut self, handle: Index) -> Option<&mut Multibody<N>>

Gets a mutable reference to the multibody identified by handle.

Returns None if the body does not exists, of if it exists but is not a multibody.

Trait Implementations

impl<N> BodySet<N> for DefaultBodySet<N>

where N: RealField + Copy,

type Handle = Index

fn get_mut( &mut self, handle: <DefaultBodySet<N> as BodySet<N>>::Handle, ) -> Option<&mut (dyn Body<N> + 'static)>

Gets a mutable reference to the body identified by handle.

fn contains(&self, handle: <DefaultBodySet<N> as BodySet<N>>::Handle) -> bool

Check if this set contains a body identified by handle.

fn foreach( &self, f: &mut dyn FnMut(<DefaultBodySet<N> as BodySet<N>>::Handle, &(dyn Body<N> + 'static)), )

Iterate through all the bodies on this set, applying the closure f on them.

Gets a reference to the two bodies identified by handle1 and handle2.
