Trait Implementations§

Source§

impl<V: Clone> Clone for ShuffleValueTree<V>

Source§

fn clone(&self) -> ShuffleValueTree<V>

Returns a copy of the value. Read more
1.0.0 · Source§

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

Performs copy-assignment from source. Read more
Source§

impl<V: Debug> Debug for ShuffleValueTree<V>

Source§

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

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

impl<V: ValueTree> ValueTree for ShuffleValueTree<V>
where V::Value: Shuffleable,

Source§

type Value = <V as ValueTree>::Value

The type of the value produced by this ValueTree.
Source§

fn current(&self) -> V::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
