Trait Tf 

pub trait Tf<T>
where
    T: NaiveDocument,
{
    // Required method
    fn tf<K>(term: K, doc: &T) -> f64
       where K: Borrow<T::Term>;
}

A strategy to calculate a weighted or unweighted term frequency (tf) score of a term from a document.

Required Methods

fn tf<K>(term: K, doc: &T) -> f64

where K: Borrow<T::Term>,

Returns the weighted or unweighted term frequency (tf) for a single term within a document.

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.
