Struct proptest::tuple::TupleValueTree

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

Common ValueTree implementation for all tuple strategies.

Implementations

impl<T> TupleValueTree<T>

pub fn new(inner: T) -> Self

Create a new TupleValueTree wrapping inner.

It only makes sense for inner to be a tuple of an arity for which the type implements ValueTree.

Trait Implementations

impl<T: Clone> Clone for TupleValueTree<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for TupleValueTree<T>

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

Formats the value using the given formatter.

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.
