Trait Translator 

Source 
pub trait Translator: Clone + BuildHasher {
    type Key: Ord + Hash + Copy;

    // Required method
    fn transform(&self, key: &[u8]) -> Self::Key;
}
Expand description

Translate keys into a new representation (often a smaller one).

§Warning

The output of Translator::transform is often used as a key in a hash table. If the output is not uniformly distributed, the performance of said hash table will degrade substantially.

Required Associated Types§

Source

type Key: Ord + Hash + Copy

The type of the internal representation of keys.

Although Translator is a BuildHasher, the Key type must still implement Hash for compatibility with any hash table that wraps Translator. We also require Ord for compatibility with ordered collections.

Required Methods§

Source

fn transform(&self, key: &[u8]) -> Self::Key

Transform a key into its new representation.

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.
