Trait Implementations

impl<M0: Clone, M1: Clone, M2: Clone, M3: Clone> Clone for Tuple4<M0, M1, M2, M3>

fn clone(&self) -> Tuple4<M0, M1, M2, M3>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<M0: Debug, M1: Debug, M2: Debug, M3: Debug> Debug for Tuple4<M0, M1, M2, M3>

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

Formats the value using the given formatter.

impl<M0: Default, M1: Default, M2: Default, M3: Default> Default for Tuple4<M0, M1, M2, M3>

fn default() -> Tuple4<M0, M1, M2, M3>

Returns the “default value” for a type.

impl<M0, T0, M1, T1, M2, T2, M3, T3> Mutate<(T0, T1, T2, T3)> for Tuple4<M0, M1, M2, M3>

where M0: Mutate<T0>, M1: Mutate<T1>, M2: Mutate<T2>, M3: Mutate<T3>,

fn mutate( &mut self, _c: &mut Candidates<'_>, (T0, T1, T2, T3): &mut (T0, T1, T2, T3), ) -> Result<()>

Pseudo-randomly mutate the given value.

fn or<M>(self, other: M) -> Or<Self, M>

where Self: Sized,

Create a new mutator that performs either this mutation or the other mutation.

fn map<F>(self, f: F) -> Map<Self, F>

where Self: Sized, F: FnMut(&mut Context, &mut T) -> Result<()>,

Map a function over the mutations produced by this mutator.

fn proj<F, U>(self, f: F) -> Proj<Self, F>

where Self: Sized, F: FnMut(&mut U) -> &mut T,

Given a projection function F: FnMut(&mut U) -> &mut T, turn this Mutate<T> into a Mutate<U>.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Borrows a mutator, rather than consuming it.
