Module joint 

Structs

DistanceJoint

(b2DistanceJoint)

Joint

Map from JointId to joint data in the solver sets. (b2Joint)

JointEdge

A joint edge connects bodies and joints together in a joint graph where each body is a node and each joint is an edge. (b2JointEdge)

JointSim

The base joint simulation data. (b2JointSim)

MotorJoint

(b2MotorJoint)

PrismaticJoint

(b2PrismaticJoint)

RevoluteJoint

(b2RevoluteJoint)

WeldJoint

(b2WeldJoint)

WheelJoint

(b2WheelJoint)

Enums

JointPayload

The per-type joint payload. The C b2JointSim stores a b2JointType type tag plus a union; the Rust port stores this tagged enum. A filter joint has no simulation data.

JointType

Joint type enumeration. (types.h: b2JointType)

Functions

create_distance_joint

(b2CreateDistanceJoint)

create_filter_joint

(b2CreateFilterJoint)

create_motor_joint

(b2CreateMotorJoint)

create_prismatic_joint

(b2CreatePrismaticJoint)

create_revolute_joint

(b2CreateRevoluteJoint)

create_weld_joint

(b2CreateWeldJoint)

create_wheel_joint

(b2CreateWheelJoint)

destroy_joint

(b2DestroyJoint)

destroy_joint_internal

Destroy a joint: unlink it from both bodies’ joint lists, the island graph, and the solver set or constraint graph that owns its sim, then free the id. (b2DestroyJointInternal — C takes the joint pointer; the Rust port takes the id.)

draw_joint

(b2DrawJoint)

get_joint_full_id

Validate a JointId and return the raw joint index. (b2GetJointFullId — C returns a pointer; Rust returns the index into world.joints)

get_joint_reaction

Reaction force/torque magnitudes for joint events. Returns (force, torque). (b2GetJointReaction — C returns through out-pointers)

get_joint_sim

Borrow a joint’s sim data mutably: constraint graph color for awake joints, otherwise the owning solver set. (b2GetJointSim)

get_joint_sim_check_type

(b2GetJointSimCheckType)

get_joint_sim_check_type_ref

Shared-reference variant of get_joint_sim_check_type.

get_joint_sim_ref

Shared-reference variant of get_joint_sim for read-only accessors. (The C b2GetJointSim is used for both; Rust needs the split.)

joint_get_angular_separation

(b2Joint_GetAngularSeparation)

joint_get_body_a

(b2Joint_GetBodyA)

joint_get_body_b

(b2Joint_GetBodyB)

joint_get_collide_connected

(b2Joint_GetCollideConnected)

joint_get_constraint_force

(b2Joint_GetConstraintForce)

joint_get_constraint_torque

(b2Joint_GetConstraintTorque)

joint_get_constraint_tuning

(b2Joint_GetConstraintTuning — C returns through out-pointers)

joint_get_force_threshold

(b2Joint_GetForceThreshold)

joint_get_linear_separation

(b2Joint_GetLinearSeparation)

joint_get_local_frame_a

(b2Joint_GetLocalFrameA)

(b2Joint_GetTorqueThreshold)

joint_get_type

(b2Joint_GetType)

joint_get_user_data

(b2Joint_GetUserData)

joint_is_valid

Joint id validity. (b2Joint_IsValid — the world-registry check collapses to the index/generation check in the registry-less port)

(b2Joint_SetCollideConnected)

joint_set_constraint_tuning

(b2Joint_SetConstraintTuning)
