Struct sticker::Numberer

pub struct Numberer<T> where
    T: Eq + Hash,  { /* fields omitted */ }

Numberer for categorical values, such as features or class labels.

Methods

impl<T> Numberer<T> where
    T: Clone + Eq + Hash, 

pub fn new(start_at: usize) -> Self

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn add(&mut self, value: T) -> usize

Add an value. If the value has already been encountered before, the corresponding number is returned.

pub fn number(&self, item: &T) -> Option<usize>

Return the number for a value.

pub fn value(&self, number: usize) -> Option<&T>

Return the value for a number.
