Struct HashSet 

pub struct HashSet<M> { /* private fields */ }

The default mutator for HashSet<T> values.

See the hash_set() function to create new instances and for example usage.

Trait Implementations

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

Return the number of mutations that mutate would register for the given value.

fn mutate( &mut self, c: &mut Candidates<'_>, value: &mut HashSet<T>, ) -> Result<()>

Pseudo-randomly mutate the given value.

fn generate_via_mutate( &mut self, context: &mut Context, iters: usize, ) -> Result<T>

where T: Sized + Default,

Generate a new value by mutating its default value iters times.

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.
