Expand description

A trait to facilitate mark-and-sweep garbage collection.

NOTE: Since there is no real need for generics here right now - the ‘key’ type is specified to avoid wrapping it.

Required Methods§

source

fn get_keys(&self) -> Result<T>

Gets all the keys currently in the database.

NOTE: This might need to be further enhanced with some sort of limit to avoid taking up too much time and memory.

source

fn remove_keys(&self, keys: T) -> Result<u32>

Removes all the keys marked for deletion.

§Arguments
  • keys - A set of keys to be removed from the database.
