Trait TFIDFEngine 

Source 
pub trait TFIDFEngine<N, K>: Send + Sync
where
    N: Num + Copy,
{
    // Required method
    fn tf_vec(
        freq: &TokenFrequency,
        token_dim_sample: &IndexSet<Box<str>>,
    ) -> (ZeroSpVec<N>, f64);

    // Provided method
    fn idf_vec(
        corpus: &Corpus,
        token_dim_sample: &Vec<Box<str>>,
    ) -> (Vec<f32>, f64) { ... }
}

Required Methods§

Source

fn tf_vec( freq: &TokenFrequency, token_dim_sample: &IndexSet<Box<str>>, ) -> (ZeroSpVec<N>, f64)

Method to generate the TF vector

§Arguments
  • freq - Token frequency
  • token_dim_sample - Token dimension sample
§Returns
  • (ZeroSpVec<N>, f64) - TF vector and value for denormalization

Provided Methods§

Source

fn idf_vec(corpus: &Corpus, token_dim_sample: &Vec<Box<str>>) -> (Vec<f32>, f64)

Method to generate the IDF vector

§Arguments
  • corpus - The corpus
  • token_dim_sample - Token dimension sample
§Returns
  • Vec<N> - The IDF vector
  • denormalize_num - Value for denormalization

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
