Struct b2ParticleHandle 

pub struct b2ParticleHandle { /* private fields */ }

Handle to a particle. Particle indices are ephemeral: the same index might refer to a different particle, from frame-to-frame. If you need to keep a reference to a particular particle across frames, you should acquire a b2ParticleHandle. Use #b2ParticleSystem::GetParticleHandleFromIndex() to retrieve the b2ParticleHandle of a particle from the particle system.

Implementations

impl b2ParticleHandle

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

Initialize the index associated with the handle to an invalid index.

impl b2ParticleHandle

pub fn GetIndex(&self) -> c_int

Get the index of the particle associated with this handle.

Trait Implementations

impl Drop for b2ParticleHandle

fn drop(self: &mut b2ParticleHandle)

Empty destructor.

impl ExternType for b2ParticleHandle

type Id = (b, _2, P, a, r, t, i, c, l, e, H, a, n, d, l, e)

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

type Kind = Opaque

impl MakeCppStorage for b2ParticleHandle

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2ParticleHandle

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 b2ParticleHandle)

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