Generate a new value tree from the given runner.

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

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

pub fn prop_map_into<O>(self) -> MapInto<Self, O> where
    O: Debug,
    Self::Value: Into<O>, 

Returns a strategy which produces values of type O by transforming Self with Into<O>.

pub fn prop_perturb<O, F>(self, fun: F) -> Perturb<Self, F> where
    F: Fn(Self::Value, TestRng) -> O,
    O: Debug, 

Returns a strategy which produces values transformed by the function fun, which is additionally given a random number generator.

pub fn prop_flat_map<S, F>(self, fun: F) -> Flatten<Map<Self, F>> where
    S: Strategy,
    F: Fn(Self::Value) -> S, 

Maps values produced by this strategy into new strategies and picks values from those strategies.

    S: Strategy,
    F: Fn(Self::Value) -> S,

pub fn prop_ind_flat_map2<S, F>(self, fun: F) -> IndFlattenMap<Self, F> where
    S: Strategy,
    F: Fn(Self::Value) -> S, 

Similar to prop_ind_flat_map(), but produces 2-tuples with the input generated from self in slot 0 and the derived strategy in slot 1.

Shuffle the contents of the values produced by this strategy.

pub fn boxed(self) -> BoxedStrategy<Self::Value> where
    Self: 'static, 

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

pub fn sboxed(self) -> SBoxedStrategy<Self::Value> where
    Self: Send + Sync + 'static, 

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