Struct proptest::strategy::UnionValueTree

pub struct UnionValueTree<T: Strategy> { /* private fields */ }

ValueTree corresponding to Union.

Trait Implementations

impl<T: Strategy> Clone for UnionValueTree<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 UnionValueTree<T>

where T::Tree: Debug,

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

Formats the value using the given formatter.

impl<T: Strategy> ValueTree for UnionValueTree<T>

type Value = <T as Strategy>::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.
