Struct b2ContactFilter 

pub struct b2ContactFilter { /* private fields */ }

Implement this class to provide collision filtering. In other words, you can implement this class if you want finer control over contact creation.

Implementations

impl b2ContactFilter

pub unsafe fn ShouldCollide( self: Pin<&mut b2ContactFilter>, fixtureA: *mut b2Fixture, fixtureB: *mut b2Fixture, ) -> bool

Return true if contact calculations should be performed between these two shapes. @warning for performance reasons this is only called when the AABBs begin to overlap.

pub unsafe fn ShouldCollide1( self: Pin<&mut b2ContactFilter>, fixture: *mut b2Fixture, particleSystem: *mut b2ParticleSystem, particleIndex: c_int, ) -> bool

Return true if contact calculations should be performed between a fixture and particle. This is only called if the b2_fixtureContactListenerParticle flag is set on the particle.

pub unsafe fn ShouldCollide2( self: Pin<&mut b2ContactFilter>, particleSystem: *mut b2ParticleSystem, particleIndexA: c_int, particleIndexB: c_int, ) -> bool

Return true if contact calculations should be performed between two particles. This is only called if the b2_particleContactListenerParticle flag is set on the particle.

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

Synthesized default constructor.

Trait Implementations

impl CopyNew for b2ContactFilter

unsafe fn copy_new( other: &b2ContactFilter, this: Pin<&mut MaybeUninit<b2ContactFilter>>, )

Synthesized copy constructor.

impl Drop for b2ContactFilter

fn drop(self: &mut b2ContactFilter)

Executes the destructor for this type.

impl ExternType for b2ContactFilter

type Id = (b, _2, C, o, n, t, a, c, t, F, i, l, t, e, r)

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

type Kind = Opaque

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

impl MakeCppStorage for b2ContactFilter

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2ContactFilter

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 b2ContactFilter)

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