Trait Distance 

pub trait Distance {
    // Required method
    fn distance(&self, other: &Self) -> u64;
}

This trait used by BKTree to tell how close are 2 objects when fuzzy searching. In case of strings, the distance function could be something like Levenshtein distance, Damerau–Levenshtein distance, Optimal string alignment distance or anything similar.

Required Methods

fn distance(&self, other: &Self) -> u64

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.
