Module predict 

Available on crate feature alloc only.

Cache-optimized tree traversal for prediction.

Standalone functions that operate on a TreeArena for traversal, prediction, and structural queries. These are decoupled from crate::tree::StreamingTree so they can be reused by the ensemble layer and tested independently.

Functions

collect_leaves

Collect every leaf NodeId reachable from root via depth-first traversal.

predict_batch

Batch prediction: compute the leaf value for each row in feature_matrix.

predict_from_root

Predict the leaf value for a single feature vector, starting from root.

traverse_to_leaf

Traverse the tree from the given root to a leaf, returning the leaf’s NodeId.

tree_depth

Compute the maximum depth of any leaf reachable from root.
