Struct ContactPoints 

pub struct ContactPoints(/* private fields */);

An opaque, fixed-capacity collection of the solved contact points carried by a CollisionEvent (at most CAPACITY).

The backing storage is a stack-allocated inline array (no heap allocation). The concrete container type is an implementation detail and is deliberately not part of the public API, so it can change without a breaking release. Interact with it through the inherent methods, IntoIterator (by value or by reference), FromIterator, or indexing.

Implementations

impl ContactPoints

pub const CAPACITY: usize = 4

Maximum number of contact points an event can hold.

pub fn new() -> ContactPoints

Create an empty set.

pub fn len(&self) -> usize

Number of contact points currently stored.

pub fn is_empty(&self) -> bool

Returns true if there are no contact points.

pub fn push(&mut self, contact: ContactPoint)

Append a contact point. Silently ignored when already at CAPACITY points.

pub fn first(&self) -> Option<&ContactPoint>

The first contact point, if any.

pub fn iter(&self) -> Iter<'_, ContactPoint>

Iterate over the contact points by reference.

pub fn as_slice(&self) -> &[ContactPoint]

View the contact points as a slice.

Trait Implementations
