Trait Implementations§

source§

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

source§

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

Returns a copy of the value. Read more

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

Performs copy-assignment from `source`. Read more
source§

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

source§

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

Formats the value using the given formatter. Read more
source§

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

§

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

The type of the value produced by this `ValueTree`.
source§

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

Returns the current value.
source§

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. Read more
source§

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. Read more
