Struct b2PrismaticJoint 

pub struct b2PrismaticJoint { /* private fields */ }

A prismatic joint. This joint provides one degree of freedom: translation along an axis fixed in bodyA. Relative rotation is prevented. You can use a joint limit to restrict the range of motion and a joint motor to drive the motion or to model joint friction.

Trait Implementations

impl AsRef<b2Joint> for b2PrismaticJoint

fn as_ref(self: &b2PrismaticJoint) -> &b2Joint

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

impl CopyNew for b2PrismaticJoint

unsafe fn copy_new( other: &b2PrismaticJoint, this: Pin<&mut MaybeUninit<b2PrismaticJoint>>, )

Synthesized copy constructor.

impl Drop for b2PrismaticJoint

fn drop(self: &mut b2PrismaticJoint)

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 b2PrismaticJoint

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

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 b2PrismaticJoint

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2PrismaticJoint

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 b2PrismaticJoint)

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