ValueTree corresponding to HashMapStrategy.

Trait Implementations

impl<K: Clone, V: Clone> Clone for HashMapValueTree<K, V> where     K: ValueTree,     V: ValueTree,     K::Value: Hash + Eq,

fn clone(&self) -> HashMapValueTree<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for HashMapValueTree<K, V> where     K: ValueTree,     V: ValueTree,     K::Value: Hash + Eq,

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<K, V> ValueTree for HashMapValueTree<K, V> where     K: ValueTree,     V: ValueTree,     K::Value: Hash + Eq,

type Value = HashMap<K::Value, V::Value>

The type of the value produced by this ValueTree.

fn current(&self) -> Self::Value

Returns the current value.

fn simplify(&mut self) -> bool

Attempts to simplify the current value. Notionally, this sets the "high" value to the current value, and the current value to a "halfway point" between high and low, rounding towards low.

fn complicate(&mut self) -> bool

Attempts to partially undo the last simplification. Notionally, this sets the "low" value to one plus the current value, and the current value to a "halfway point" between high and the new low, rounding towards low.
