You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: traversal.rs
    path of file: ./repos/parry/src/partitioning/qbvh
    
    the code of the file until where you have to start completion: use crate::bounding_volume::{Aabb, SimdAabb};
use crate::math::Real;
use 
    
    pub fn intersect_aabb(&self, aabb: &Aabb, out: &mut Vec<LeafData>) {
        if self.nodes.is_empty() {
            return;
        }

        // Special case for the root.
        let mut stack = vec![0u32];
        let simd_aabb = SimdAabb::splat(*aabb);
        while let Some(inode) = stack.pop() {
            let node = &self.nodes[inode as usize];
            let intersections = node.simd_aabb.intersects(&simd_aabb);
            let bitmask = intersections.bitmask();

            for ii in 0..SIMD_WIDTH {
                if (bitmask & (1 << ii)) != 0 {
                    if node.is_leaf() {
                        // We found a leaf!
                        // Unfortunately, invalid Aabbs return a intersection as well.
                        if let Some(proxy) = self.proxies.get_at(node.children[ii] as usize) {
                            out.push(proxy.data);
                        }
                    } else {
                        // Internal node, visit the child.
                        // Unfortunately, we have this check because invalid Aabbs
                        // return a intersection as well.
                        if node.children[ii] as usize <= self.nodes.len() {
                            stack.push(node.children[ii]);
                        }
                    }
                }
            }
        }
    }
