Struct UnsafeCellMutator 

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

A mutator for core::cell::UnsafeCell<T> values.

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

Trait Implementations

impl<M: Clone> Clone for UnsafeCellMutator<M>

fn clone(&self) -> UnsafeCellMutator<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug> Debug for UnsafeCellMutator<M>

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

Formats the value using the given formatter.

impl<M: Default> Default for UnsafeCellMutator<M>

fn default() -> UnsafeCellMutator<M>

Returns the “default value” for a type.

impl<M, T> Generate<UnsafeCell<T>> for UnsafeCellMutator<M>

where M: Generate<T>,

fn generate(&mut self, ctx: &mut Context) -> Result<UnsafeCell<T>>

Generate a random T value from scratch.

impl<M, T> Mutate<UnsafeCell<T>> for UnsafeCellMutator<M>

where M: Mutate<T>,

fn mutate( &mut self, c: &mut Candidates<'_>, value: &mut UnsafeCell<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.
