Struct b2PrismaticJointDef 

pub struct b2PrismaticJointDef { /* private fields */ }

Prismatic joint definition. This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. Using local anchors and a local axis helps when saving and loading a game.

Implementations

impl b2PrismaticJointDef

pub unsafe fn Initialize( self: Pin<&mut b2PrismaticJointDef>, bodyA: *mut b2Body, bodyB: *mut b2Body, anchor: &b2Vec2, axis: &b2Vec2, )

Initialize the bodies, anchors, axis, and reference angle using the world anchor and unit world axis.

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

Trait Implementations

impl AsRef<b2JointDef> for b2PrismaticJointDef

fn as_ref(self: &b2PrismaticJointDef) -> &b2JointDef

Converts this type into a shared reference of the (usually inferred) input type.

impl CopyNew for b2PrismaticJointDef

unsafe fn copy_new( other: &b2PrismaticJointDef, this: Pin<&mut MaybeUninit<b2PrismaticJointDef>>, )

Synthesized copy constructor.

impl Drop for b2PrismaticJointDef

fn drop(self: &mut b2PrismaticJointDef)

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 b2PrismaticJointDef

type Id = (b, _2, P, r, i, s, m, a, t, i, c, J, o, i, n, t, D, e, f)

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 b2PrismaticJointDef

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2PrismaticJointDef

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 b2PrismaticJointDef)

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

impl MoveNew for b2PrismaticJointDef

unsafe fn move_new( other: Pin<MoveRef<'_, b2PrismaticJointDef>>, this: Pin<&mut MaybeUninit<b2PrismaticJointDef>>, )

Synthesized move constructor.
