Struct un_algebra::tests::config::prop::collection::HashMapValueTree

pub struct HashMapValueTree<K, V>(_)
 where
    K: ValueTree,
    V: ValueTree,
    <K as ValueTree>::Value: Hash,
    <K as ValueTree>::Value: Eq;

ValueTree corresponding to HashMapStrategy.

Trait Implementations

impl<K, V> Debug for HashMapValueTree<K, V> where
    K: Debug + ValueTree,
    V: Debug + ValueTree,
    <K as ValueTree>::Value: Hash,
    <K as ValueTree>::Value: Eq, 

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

Formats the value using the given formatter.

impl<K, V> Clone for HashMapValueTree<K, V> where
    K: Clone + ValueTree,
    V: Clone + ValueTree,
    <K as ValueTree>::Value: Hash,
    <K as ValueTree>::Value: Eq, 

fn clone(&self) -> HashMapValueTree<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K, V> ValueTree for HashMapValueTree<K, V> where
    K: ValueTree,
    V: ValueTree,
    <K as ValueTree>::Value: Hash,
    <K as ValueTree>::Value: Eq, 

type Value = HashMap<<K as ValueTree>::Value, <V as ValueTree>::Value, RandomState>

The type of the value produced by this ValueTree.

fn current(&self) -> <HashMapValueTree<K, V> as ValueTree>::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.
