* Converts a {@linkcode ReadableStream} of {@linkcode Uint8Array}s to a
|
|
* {@linkcode Blob}. Works the same as {@linkcode Response.blob}.
|
|
*
|
|
* @param stream A `ReadableStream` of `Uint8Array`s to convert into a `Blob`.
|
|
* @returns A `Promise` that resolves to the `Blob`.
|
|
*
|
|
* @example Basic usage
|
|
* ```ts
|
|
* import { toBlob } from "@std/streams/to-blob";
|
|
* import { assertEquals } from "@std/assert";
|
|
*
|
|
* const stream = ReadableStream.from([
|
|
* new Uint8Array([1, 2]),
|
|
* new Uint8Array([3, 4, 5]),
|
|
* ]);
|
|
* const blob = await toBlob(stream);
|
|
* assertEquals(blob.size, 5);
|
|
* ```
