Module serialize 

Optional JSON serialization for fitted transformers (gated on the serde feature).

Leaf transformers derive Serialize/Deserialize; use save_json and load_json to persist fitted state. Pipeline and ColumnTransformer are also serializable via the TransformerKind enum wrapper.

Functions

from_json

Deserialize a transformer from a JSON string.

load_json

Read a transformer from the JSON file at path.

save_json

Serialize a fitted transformer and write it to the file at path.

to_json

Serialize a fitted transformer to a pretty-printed JSON string.
