Struct Memory 

pub struct Memory { /* private fields */ }

A change store in memory, i.e. basically a hash table.

impl Clone for Memory

fn clone(&self) -> Memory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Memory

fn default() -> Memory

Returns the “default value” for a type.
