Struct b2WorldManifold 

#[repr(C)]
pub struct b2WorldManifold {
    pub normal: b2Vec2,
    pub points: [b2Vec2; 2],
    pub separations: [f32; 2],
}

This is used to compute the current state of a contact manifold.

Fields

normal: b2Vec2

< world vector pointing from A to B

points: [b2Vec2; 2]

< world contact point (point of intersection)

separations: [f32; 2]

< a negative value indicates overlap, in meters

Implementations

impl b2WorldManifold

pub unsafe fn Initialize( self: Pin<&mut b2WorldManifold>, manifold: *const b2Manifold, xfA: &b2Transform, radiusA: f32, xfB: &b2Transform, radiusB: f32, )

Evaluate the manifold with supplied transforms. This assumes modest motion from the original state. This does not change the point count, impulses, etc. The radii must come from the shapes that generated the manifold.

pub fn new() -> impl New<Output = Self>

Synthesized default constructor.

Trait Implementations

impl CopyNew for b2WorldManifold

unsafe fn copy_new( other: &b2WorldManifold, this: Pin<&mut MaybeUninit<b2WorldManifold>>, )

Synthesized copy constructor.

impl Drop for b2WorldManifold

fn drop(self: &mut b2WorldManifold)

Synthesized destructor.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ExternType for b2WorldManifold

type Id = (b, _2, W, o, r, l, d, M, a, n, i, f, o, l, d)

A type-level representation of the type’s C++ namespace and type name.

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

impl MakeCppStorage for b2WorldManifold

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2WorldManifold

Allocates heap space for this type in C++ and return a pointer to that space, but do not initialize that space (i.e. do not yet call a constructor).

unsafe fn free_uninitialized_cpp_storage(arg0: *mut b2WorldManifold)

Frees a C++ allocation which has not yet had a constructor called.

impl MoveNew for b2WorldManifold

unsafe fn move_new( other: Pin<MoveRef<'_, b2WorldManifold>>, this: Pin<&mut MaybeUninit<b2WorldManifold>>, )

Synthesized move constructor.
