Struct Map

pub struct Map<T: ?Sized, F>(/* private fields */);

Trait Implementations

impl<T: Clone + ?Sized, F: Clone> Clone for Map<T, F>

fn clone(&self) -> Map<T, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ?Sized, F: Debug> Debug for Map<T, F>

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

Formats the value using the given formatter.

impl<G: Generate + ?Sized, T, F: Fn(G::Item) -> T + Clone> Generate for Map<G, F>

type Item = T

type Shrink = Map<<G as Generate>::Shrink, F>

fn generate(&self, state: &mut State) -> Self::Shrink

Primary method of this trait. It generates a Shrink instance that will be able to produce values of type Generate::Item and shrink itself.

fn constant(&self) -> bool

Returns true if the generator will always produce the same item. This is used in some optimizations to prevent redundant generations.

impl<S: Shrink, T, F: Fn(S::Item) -> T + Clone> Shrink for Map<S, F>

type Item = T

fn item(&self) -> Self::Item

fn shrink(&mut self) -> Option<Self>
