Struct proptest::collection::VecStrategy

pub struct VecStrategy<T: Strategy> { /* fields omitted */ }

Strategy to create Vecs with a length in a certain range.

Created by the vec() function in the same module.

Trait Implementations

impl<T: Clone + Strategy> Clone for VecStrategy<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Strategy> Debug for VecStrategy<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T: Strategy> Strategy for VecStrategy<T>

type Value = VecValueTree<T::Value>

The value tree generated by this Strategy.

fn new_value(&self, runner: &mut TestRunner) -> Result<Self::Value, String>

Generate a new value tree from the given runner.

fn prop_map<O: Debug, F: Fn(<Self::Value as ValueTree>::Value) -> O>(
    self,
    fun: F
) -> Map<Self, F> where
    Self: Sized, 

Returns a strategy which produces values transformed by the function fun.

fn prop_filter<F: Fn(&<Self::Value as ValueTree>::Value) -> bool>(
    self,
    whence: String,
    fun: F
) -> Filter<Self, F> where
    Self: Sized, 

Returns a strategy which only produces values accepted by fun.

fn prop_union(self, other: Self) -> Union<Self> where
    Self: Sized, 

Returns a strategy which picks uniformly from self and other.

fn boxed(self) -> BoxedStrategy<<Self::Value as ValueTree>::Value> where
    Self: Sized + 'static, 

Erases the type of this Strategy so it can be passed around as a simple trait object.
