Trait Implementations§

§

impl StateR for EmptyState

§

fn get(&self, _: Key) -> Option<Value>

§

fn contains(&self, _: Key) -> bool

§

fn debug_iter<'a>(&'a self) -> Box<dyn Iterator<Item = (Key, Value)> + 'a>

This method is for debugging. If the implementation does not provide such functionality, it defaults to an empty iterator.
