Struct proptest::strategy::FlattenValueTree

pub struct FlattenValueTree<S: ValueTree> where
    S::Value: Strategy, { /* private fields */ }

The ValueTree produced by Flatten.

Trait Implementations

impl<S: ValueTree> Clone for FlattenValueTree<S> where
    S::Value: Strategy + Clone,
    S: Clone,
    <S::Value as Strategy>::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<S: ValueTree> Debug for FlattenValueTree<S> where
    S::Value: Strategy,
    S: Debug,
    <S::Value as Strategy>::Tree: Debug, 

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

Formats the value using the given formatter.

impl<S: ValueTree> ValueTree for FlattenValueTree<S> where
    S::Value: Strategy, 

type Value = <<S as ValueTree>::Value 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.
