[−][src]Struct nphysics2d::solver::ImpulseCache
A cache for impulses.
Methods
impl<N: Copy + Zero> ImpulseCache<N>
[src]
pub fn new() -> Self
[src]
Create a new empty cache.
pub fn clear(&mut self)
[src]
Clear the cache.
pub fn len(&self) -> usize
[src]
The number of impulses on this cache.
pub fn contains(&self, contact_id: GenerationalId) -> bool
[src]
Test if the cache already contains the specified contact.
pub fn get(&self, contact_id: GenerationalId) -> N
[src]
Get the impulse stored for the specified contact.
Returns 0 if no cache entry is registered for this contact.
pub fn entry_id(&mut self, contact_id: GenerationalId) -> usize
[src]
Retrieve the index on the cache vector associated to the given contact.
