Struct mutatis::mutators::U128

pub struct U128 { /* private fields */ }

A mutator for u128 values.

See the u128() function to create new instances and for example usage.

Trait Implementations

impl Clone for U128

fn clone(&self) -> U128

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for U128

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

Formats the value using the given formatter.

impl Default for U128

fn default() -> U128

Returns the “default value” for a type.

impl Generate<u128> for U128

fn generate(&mut self, ctx: &mut Context) -> Result<u128>

Generate a random T value from scratch.

impl Mutate<u128> for U128

fn mutate(&mut self, c: &mut Candidates<'_>, value: &mut u128) -> 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.

impl MutateInRange<u128> for U128

fn mutate_in_range( &mut self, c: &mut Candidates<'_>, value: &mut u128, range: &RangeInclusive<u128>, ) -> Result<()>

Mutate a value, ensuring that the resulting mutation is within the given range.
