how to resolve the error " inconsistent accessibility"

public struct HandPositions{ public Irrelevant.Assets.Script.Vector3 left, right; `` // 3d world positions of hands { ERROR APPEARS HERE IN LEFT AND RIGHT}

 public HandPositions (NiteWrapper.SkeletonJointTransformation leftHand, NiteWrapper.SkeletonJointTransformation rightHand) {
     left = new Irrelevant.Assets.Script.Vector3(leftHand.pos.x, leftHand.pos.y, leftHand.pos.z);
     right = new Irrelevant.Assets.Script.Vector3(rightHand.pos.x, rightHand.pos.y, rightHand.pos.z);
 }

}
