Trait StateR

pub trait StateR: Send + Sync {
    // Required method
    fn get(&self, key: Key) -> Option<Value>;

    // Provided method
    fn debug_iter<'a>(&'a self) -> Box<dyn Iterator<Item = (Key, Value)> + 'a> { ... }
}

Read-only low-level state used by Lyquor Virtual Machine (LVM).

Required Methods

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

Provided Methods

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.
