Struct ComposedTransformer

pub struct ComposedTransformer<Tr> { /* private fields */ }

Transformer composed from a list of transformers

The transformers are stacked in the order they are given in the list, with number of features per trasnformer specified.

Implementations

impl<Tr> ComposedTransformer<Tr>

where Tr: TransformerPropsTrait,

pub fn new( transformers: impl Into<Vec<(Tr, usize)>>, ) -> Result<Self, ComposedTransformerConstructionError>

Create a new composed transformer from a list of transformers and the number of features they take as input.

pub fn from_transformers( transformers: impl IntoIterator<Item = Tr>, ) -> Result<Self, ComposedTransformerConstructionError>

Create a new composed transformer from a list of transformers assumed that all of them may take a single feature as input.
