Struct proptest::option::OptionValueTree

pub struct OptionValueTree<T>(_)
 where
    T: Strategy;

ValueTree type corresponding to OptionStrategy.

Trait Implementations

impl<T: Strategy> Clone for OptionValueTree<T> where
    T::Tree: Clone, 

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Strategy> Debug for OptionValueTree<T> where
    T::Tree: Debug, 

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

Formats the value using the given formatter.

impl<T> ValueTree for OptionValueTree<T> where
    T: Strategy, 

type Value = Option<T::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.
