Struct NonZeroI32 

pub struct NonZeroI32 { /* private fields */ }

A mutator for NonZero<i32> values.

See the non_zero_i32() function to create new instances and for example usage.

Trait Implementations

impl Clone for NonZeroI32

fn clone(&self) -> NonZeroI32

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonZeroI32

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

Formats the value using the given formatter.

impl Default for NonZeroI32

fn default() -> NonZeroI32

Returns the “default value” for a type.

impl Generate<NonZero<i32>> for NonZeroI32

fn generate(&mut self, ctx: &mut Context) -> Result<NonZero<i32>>

Generate a random T value from scratch.

impl Mutate<NonZero<i32>> for NonZeroI32

fn mutate( &mut self, c: &mut Candidates<'_>, value: &mut NonZero<i32>, ) -> 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.
