Trait nphysics3d::joint::UnitJoint [−][src]
pub trait UnitJoint<N: RealField + Copy>: Joint<N> { fn position(&self) -> N; fn motor(&self) -> &JointMotor<N, N>; fn min_position(&self) -> Option<N>; fn max_position(&self) -> Option<N>; }
Expand description
Trait implemented by joints using the reduced-coordinates approach and allowing only one degree of freedom.
Required methods
fn motor(&self) -> &JointMotor<N, N>
fn motor(&self) -> &JointMotor<N, N>
The motor applied to the degree of freedom of the unit joitn.
fn min_position(&self) -> Option<N>
fn min_position(&self) -> Option<N>
The lower limit, if any, set to the generalized coordinate of this unit joint.
fn max_position(&self) -> Option<N>
fn max_position(&self) -> Option<N>
The upper limit, if any, set to the generalized coordinate of this unit joint.
Implementations
Returns true if the trait object wraps an object of type __T
.
Returns a boxed object from a boxed trait object if the underlying object is of type
__T
. Returns the original boxed trait if it isn’t.
Returns an Rc
-ed object from an Rc
-ed trait object if the underlying object is of
type __T
. Returns the original Rc
-ed trait if it isn’t.
Returns a reference to the object within the trait object if it is of type __T
, or
None
if it isn’t.
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn’t.
