Struct b2RevoluteJoint 

pub struct b2RevoluteJoint { /* private fields */ }

A revolute joint constrains two bodies to share a common point while they are free to rotate about the point. The relative rotation about the shared point is the joint angle. You can limit the relative rotation with a joint limit that specifies a lower and upper angle. You can use a motor to drive the relative rotation about the shared point. A maximum motor torque is provided so that infinite forces are not generated.

Trait Implementations

impl AsRef<b2Joint> for b2RevoluteJoint

fn as_ref(self: &b2RevoluteJoint) -> &b2Joint

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

impl CopyNew for b2RevoluteJoint

unsafe fn copy_new( other: &b2RevoluteJoint, this: Pin<&mut MaybeUninit<b2RevoluteJoint>>, )

Synthesized copy constructor.

impl Drop for b2RevoluteJoint

fn drop(self: &mut b2RevoluteJoint)

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 b2RevoluteJoint

type Id = (b, _2, R, e, v, o, l, u, t, e, 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 b2RevoluteJoint

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2RevoluteJoint

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 b2RevoluteJoint)

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