@rimbu/stream

A Stream is an Iterable-like structure that represents a source that can stream values when requested. The source is unspecified, it may be a materialized object (e.g. an Array), or a calculated sequence (e.g. the fibonacci numbers). However, unlike an Iterable, a Stream offers many methods to change the values produced by the Stream, before it is consumed, without the need to materialize intermediate instances.

This package exports the following main types:

Name	Description
FastIterable<T>	an Iterable that supports faster iterating than the Iterable type
FastIterator<T>	an Iterator that supports faster iterating than the Iterator type
Stream<T>	an Iterable-like structure that represents a source that can produce values of type T when requested
Streamable<T>	an interface requiring that an object has a .stream() method
StreamSource<T>	a convenience type that covers all types that can be automatically converted to a Stream

Installation

All types are exported through @rimbu/core. It is recommended to use this package.

To install separately:

yarn add @rimbu/stream

or

npm i @rimbu/stream

recommended tsconfig settings

Rimbu uses advanced and recursive typing, potentially making the TypeScript compiler quite slow in some cases, or causing infinite recursion. It is recommended to set the following values in the tsconfig.json file of your project:

{
  "compilerOptions": {
    "skipLibCheck": true,
    "noStrictGenericChecks": true
  }
}

Usage

import { Stream } from '@rimbu/stream';

console.log(Stream.range({ start: 10, amount: 15 }).toArray());
