Struct proptest::array::ArrayValueTree

pub struct ArrayValueTree<T> { /* private fields */ }

A ValueTree operating over a fixed-size array.

Trait Implementations

impl<T: Clone> Clone for ArrayValueTree<T>

fn clone(&self) -> ArrayValueTree<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ArrayValueTree<T>

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

Formats the value using the given formatter.

impl<T: ValueTree, const N: usize> ValueTree for ArrayValueTree<[T; N]>

type Value = [<T as ValueTree>::Value; N]

The type of the value produced by this ValueTree.

fn current(&self) -> [T::Value; N]

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.
