Struct BvhResult 

pub struct BvhResult<'id, B: BvhBuilder> { /* private fields */ }

Result of a build, valid only inside the generative scope. Branded by 'id.

Implementations

impl<'id, B: BvhBuilder> BvhResult<'id, B>

pub fn root(&self) -> Option<&B::Node<'id>>

The root node, or None for an empty tree (zero primitives).

pub fn root_ptr(&self) -> Option<NodePtr<'id, B::Node<'id>>>

The root handle.

pub fn resolve(&self, p: NodePtr<'id, B::Node<'id>>) -> &B::Node<'id>

Resolve a child handle to a node reference. Safe with no runtime check: the 'id brand proves the handle came from this same build, and the arena cannot have been freed or rebuilt – the generative build_scoped closure that produced this BvhResult holds the &mut Bvh exclusively for its whole duration, so no rebuild or drop can run while 'id is live. (The returned reference borrows self, tying it to the result handle.)
