Struct proptest::collection::HashSetValueTree

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

Available on crate feature std only.

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
