Struct proptest::result::MaybeOkValueTree

pub struct MaybeOkValueTree<T, E>(_) 
where
    T: Strategy,
    E: Strategy;

ValueTree type corresponding to MaybeOk.

Trait Implementations

impl<T: Strategy, E: Strategy> Clone for MaybeOkValueTree<T, E> where
    T::Tree: Clone,
    E::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, E: Strategy> Debug for MaybeOkValueTree<T, E> where
    T::Tree: Debug,
    E::Tree: Debug, 

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

Formats the value using the given formatter.

impl<T, E> ValueTree for MaybeOkValueTree<T, E> where
    T: Strategy,
    E: Strategy, 

type Value = Result<<T as Strategy>::Value, <E 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.
