Implementations

impl<T> Encoder<T> where
    T: Hash + Eq + Clone + Debug, [src]

pub fn new(enctype: Option<EncoderType>) -> Encoder<T>[src]

pub fn fit(&mut self, data: &Vec<T>, config: &Config<T>)[src]

Fit label encoder given the type (ordinal, one-hot, custom)

pub fn transform(&self, data: &Vec<T>) -> Transform[src]
