Struct EitherKleisli 

pub struct EitherKleisli<E, A, B> {
    pub run: Box<dyn Fn(A) -> OxiEither<B, E>>,
}

A Kleisli arrow A → Either E B in the Either monad’s Kleisli category.

Fields

run: Box<dyn Fn(A) -> OxiEither<B, E>>

The underlying function from A to OxiEither<B, E>.

Implementations

impl<E: 'static, A: 'static, B: 'static> EitherKleisli<E, A, B>

pub fn new<F: Fn(A) -> OxiEither<B, E> + 'static>(f: F) -> Self

Construct a new Kleisli arrow from a function.

pub fn apply(&self, a: A) -> OxiEither<B, E>

Apply the Kleisli arrow to an input.

pub fn compose<C: 'static>( self, g: EitherKleisli<E, B, C>, ) -> EitherKleisli<E, A, C>

where E: Clone + 'static,

Compose two Kleisli arrows: (f >=> g)

pub fn lift_fn<F: Fn(A) -> B + 'static>(f: F) -> Self

Lift a plain function into the Kleisli category (i.e., return ∘ f).
