Struct mutatis::mutators::Map

pub struct Map<M, F> { /* private fields */ }

A mutator combinator for mapping a function over the mutations produced by another mutator.

See the map method on the Mutate trait for details and example usage.

Trait Implementations

impl<M: Clone, F: Clone> Clone for Map<M, F>

fn clone(&self) -> Map<M, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<M: Debug, F: Debug> Debug for Map<M, F>

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

Formats the value using the given formatter.

impl<M, F, T> Mutate<T> for Map<M, F>

where M: Mutate<T>, F: FnMut(&mut Context, &mut T) -> Result<()>,

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