Struct GraphGeneratableEffectWitness 

pub struct GraphGeneratableEffectWitness<E, L>(/* private fields */);

HKT witness type for the graph generatable effect system.

This type is used internally by the HKT machinery to provide type-level evidence for the effect system’s structure.

Trait Implementations

impl<E: Clone, L: Clone + Default + LogAppend> Applicative<GraphGeneratableEffectWitness<E, L>> for GraphGeneratableEffectWitness<E, L>

fn pure<T>(value: T) -> <Self as HKT>::Type<T>

Lifts a pure value into the minimal applicative context F::Type<T>.

fn apply<A, B, Func>( f_ab: <Self as HKT>::Type<Func>, m_a: <Self as HKT>::Type<A>, ) -> <Self as HKT>::Type<B>

where Func: FnMut(A) -> B, A: Clone,

Applies a function wrapped in a context (f_ab) to a value wrapped in a context (f_a).

impl<E: Clone, L: Clone> Functor<GraphGeneratableEffectWitness<E, L>> for GraphGeneratableEffectWitness<E, L>

fn fmap<A, B, Func>( m_a: <Self as HKT>::Type<A>, f: Func, ) -> <Self as HKT>::Type<B>

where Func: FnMut(A) -> B,

Applies a function f to the value inside the container m_a.

impl<E, L> HKT for GraphGeneratableEffectWitness<E, L>

type Type<T> = GraphGeneratableEffect<T, E, L>

The Generic Associated Type (GAT) that represents the type constructor. The <T> is the “hole” in the type constructor (e.g., Option<T>).

impl<E, L> HKT3<E, L> for GraphGeneratableEffectWitness<E, L>

type Type<T> = GraphGeneratableEffect<T, E, L>

The GAT that represents the remaining type constructor. The resulting kind is * -> * (one hole <T> remaining).

impl<E: Clone, L: Clone + Default + LogAppend> Monad<GraphGeneratableEffectWitness<E, L>> for GraphGeneratableEffectWitness<E, L>

fn bind<A, B, Func>( m_a: <Self as HKT>::Type<A>, f: Func, ) -> <Self as HKT>::Type<B>

where Func: FnMut(A) -> <Self as HKT>::Type<B>,

Chains a computation from an effectful value, flattening the result. This is the core sequencing operation of a Monad.
