class AtomExtensions Source #

Methods

method IObservable<A> OnChange <A> (this Atom<A> atom) Source #

Observe changes to the Atom

Parameters

type A

Value type

param atom

Atom to observe

returns

Observable atom

method IObservable<A> Latest <A> (this Atom<A> atom) Source #

Creates an observable that watches for changes to the Atom, but also gets primed with the initial state on subscription, so there's always at least one value that flows downstream.

Parameters

type A

class EffRxExtensions Source #

Methods

method Eff<Unit> Consume <A> ( this IObservable<A> ma, Func<A, Eff<Unit>> next) Source #

Consume an observable stream

Each item is passed to the next function. When the stream completes the Aff returns which allows subsequent operations to be composed.

Parameters

type A

Bound type

param ma

Observable to consume

param next

Next function to call

param token

Cancellation token

returns

Aff of unit

method Eff<S> Fold <S, A> (this IObservable<A> ma, S initialState, Func<S, A, Eff<S>> next) Source #

Fold an observable stream

Each item is passed to the next function, with a state value. The state is aggregated over the stream by passing the return value from next to the subsequent calls. When the stream completes, the aggregate state is returned.

Parameters

type A

Bound type

param ma

Observable to fold

param next

Next function to call

param token

Cancellation token

returns

Aff of S
