pub struct ShuffleValueTree<V> { /* fields omitted */ }

ValueTree shuffling adaptor.

See Strategy::prop_shuffle().

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

type Value = V::Value

The type of the value produced by this ValueTree.

fn current(&self) -> V::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.
