@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 |
For complete documentation please visit the Stream page in the Rimbu Docs, or directly see the Rimbu Stream API Docs.
Or Try Out Rimbu in CodeSandBox.
Installation
For convenience, all main types are also exported through @rimbu/core
.
To install separately:
Yarn/NPM
yarn add @rimbu/stream
or
npm i @rimbu/stream
Deno
For Deno, the following approach is recommended:
In the root folder of your project, create or edit a file called import_map.json
with the following contents (where you should replace x.y.z
with the desired version of Rimbu):
{
"imports": {
"@rimbu/": "https://deno.land/x/rimbu@x.y.z/"
}
}
Note: The trailing slashes are important!
In this way you can use relative imports from Rimbu in your code, like so:
import { List } from '@rimbu/core/mod.ts';
import { HashMap } from '@rimbu/hashed/mod.ts';
Note that for sub-packages, due to conversion limitations it is needed to import the index.ts
instead of mod.ts
, like so:
import { HashMap } from '@rimbu/hashed/map/index.ts';
To run your script (let’s assume the entry point is in src/main.ts
):
deno run --import-map import_map.json src/main.ts
Usage
import { Stream } from '@rimbu/stream';
console.log(Stream.range({ start: 10, amount: 15 }).toArray());
