Struct FunctionTransformer 

pub struct FunctionTransformer<F: Float> { /* private fields */ }

A transformer that applies an arbitrary function to the data.

Implements FitTransform so it can be used directly in a Pipeline. The fit step is a no-op — only the transform function is called.

Example

use anofox_ml_core::{Pipeline, FunctionTransformer};

let log_transform = FunctionTransformer::new(|x: &Array2<f64>| {
    Ok(x.mapv(|v| v.ln()))
});

let pipeline = Pipeline::new()
    .push_transformer("log", log_transform);
