Detailed Description

template<typename T>
struct ppforest2::serialization::Export< T >

A model bundled with its export metadata and optional metrics.

Represents the full JSON export format: { model_type, model, config, meta, [metrics] }.

Use j.get<Export<Tree>>() or j.get<Export<Model::Ptr>>() to deserialize a full export, and model_export.to_json() to serialize.

For Export<Model::Ptr>, construct with training data to compute metrics automatically, or use compute_metrics() after construction.
