Classes

AsyncReducer.Base

A base class that can be used to easily create AsyncReducer instances.

Variables

v AsyncReducer.and	Returns an `AsyncReducer` that takes boolean values and outputs true if all input values are true, and false otherwise.
v AsyncReducer.average	A `Reducer` that calculates the average of all given numberic input values.
v AsyncReducer.count	Returns an `AsyncReducer` that remembers the amount of input items provided.
v AsyncReducer.first	Returns an `AsyncReducer` that remembers the first input value.
v AsyncReducer.firstWhere	Returns an `AsyncReducer` that remembers the first input value for which the given `pred` function returns true.
v AsyncReducer.isEmpty	Returns an `AsyncReducer` that outputs true if no input values are received, false otherwise.
v AsyncReducer.last	Returns an `AsyncReducer` that remembers the last input value.
v AsyncReducer.lastWhere	Returns an `AsyncReducer` that remembers the last input value for which the given `pred` function returns true.
v AsyncReducer.max	Returns a `Reducer` that remembers the maximum value of the numberic inputs.
v AsyncReducer.maxBy	Returns a `Reducer` that remembers the maximum value of the inputs using the given `compFun` to compare input values
v AsyncReducer.min	Returns a `Reducer` that remembers the minimum value of the numberic inputs.
v AsyncReducer.minBy	Returns a `Reducer` that remembers the minimum value of the inputs using the given `compFun` to compare input values
v AsyncReducer.nonEmpty	Returns an `AsyncReducer` that outputs true if one or more input values are received, false otherwise.
v AsyncReducer.or	Returns an `AsyncReducer` that takes boolean values and outputs true if one or more input values are true, and false otherwise.
v AsyncReducer.product	A `Reducer` that calculates the product of all given numeric input values.
v AsyncReducer.sum	A `Reducer` that sums all given numeric input values.

Functions

f AsyncReducer.combineArr	Returns an `AsyncReducer` that combines multiple input `reducers` by providing input values to all of them and collecting the outputs in an array.
f AsyncReducer.combineObj	Returns an `AsyncReducer` that combines multiple input `reducers` by providing input values to all of them and collecting the outputs in the shape of the given object.
f AsyncReducer.contains	Returns an `AsyncReducer` that outputs false as long as the given `elem` has not been encountered in the input values, true otherwise.
f AsyncReducer.create	Returns an `AsyncReducer` with the given options:
f AsyncReducer.createMono	Returns an `AsyncReducer` of which the input, state, and output types are the same.
f AsyncReducer.createOutput	Returns an `AsyncReducer` of which the state and output types are the same.
f AsyncReducer.every	Returns an `AsyncReducer` that ouputs true as long as all input values satisfy the given `pred`, false otherwise.
f AsyncReducer.from
f AsyncReducer.join	Returns a `Reducer` that joins the given input values into a string using the given options.
f AsyncReducer.some	Returns a `Reducer` that ouputs false as long as no input value satisfies given `pred`, true otherwise.
f AsyncReducer.toArray	Returns an `AsyncReducer` that collects received input values in an array, and returns a copy of that array as an output value when requested.
f AsyncReducer.toJSMap	Returns a `AsyncReducer` that collects received input tuples into a mutable JS Map, and returns a copy of that map when output is requested.
f AsyncReducer.toJSObject	Returns an `AsyncReducer` that collects 2-tuples containing keys and values into a plain JS object, and returns a copy of that object when output is requested.
f AsyncReducer.toJSSet	Returns an `AsyncReducer` that collects received input values into a mutable JS Set, and returns a copy of that map when output is requested.

Interfaces

AsyncReducer.Impl

type alias AsyncReducer

Re-export

import { type AsyncReducer } from "https://deno.land/x/rimbu@0.13.1/core/mod.ts";

An AsyncReducer is a stand-alone asynchronous calculation that takes input values of type I, and, when requested, produces an output value of type O.

Type Parameters

optional

O = I

definition: AsyncReducer.Impl<I, O, unknown>
