Struct proptest::collection::HashSetValueTree

pub struct HashSetValueTree<T>(/* private fields */)
where
    T: ValueTree,
    T::Value: Hash + Eq;

ValueTree corresponding to HashSetStrategy.

Trait Implementations

impl<T> Clone for HashSetValueTree<T>

where T: ValueTree + Clone, T::Value: Hash + Eq,

fn clone(&self) -> HashSetValueTree<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for HashSetValueTree<T>

where T: ValueTree + Debug, T::Value: Hash + Eq,

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

Formats the value using the given formatter.

impl<T> ValueTree for HashSetValueTree<T>

where T: ValueTree, T::Value: Hash + Eq,

type Value = HashSet<<T as ValueTree>::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.
