fn mutate( &mut self, mutations: &mut Candidates<'_>, value: &mut Scenario, ) -> Result<()>

Pseudo-randomly mutate the given value.

fn mutation_count(&self, value: &Scenario, shrink: bool) -> Option<u32>

Return the number of mutations that [mutate][Mutate::mutate] would register for 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<(), Error>,

Map a function over the mutations produced by this mutator.

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

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

where Self: Sized,

Borrows a mutator, rather than consuming it.

where __S: Serializer,

Serialize this value into the given Serde serializer.
