Struct Cons 

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

Allows constructing the Observer computation by the specified function.

Trait Implementations

impl<F: Clone, M: Clone, T: Clone> Clone for Cons<F, M, T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F, M, T> Observer for Cons<F, M, T>

where F: Fn(&M, &Point<'_>) -> Result<T>,

type Message = M

The outer message that the observer reacts to.

type Item = T

The type of the item that the computation returns.

fn and_then<U, F>(self, f: F) -> AndThen<Self, U, F>

where Self: Sized, U: Observer<Message = Self::Message>, F: Fn(Self::Item) -> U,

Bind the current computation with its continuation within the resulting computation.

fn map<B, F>(self, f: F) -> Map<Self, B, F>

where Self: Sized, F: Fn(Self::Item) -> B,

Map the current computation using the specified transform.

fn zip<U>(self, other: U) -> Zip<Self, U>

where Self: Sized, U: Observer<Message = Self::Message>,

Zip the current computation with another one within the resulting computation.

fn ap<U, B>(self, other: U) -> Ap<Self, U, B>

where Self: Sized, Self::Item: Fn(U::Item) -> B, U: Observer<Message = Self::Message>,

The function application.

fn into_boxed(self) -> ObserverBox<Self::Message, Self::Item>

where Self: Sized + Clone + 'static,

Convert into a boxed value.
