TS 里引入fast-buffer.ts库 再详细讲解如何使用

To use the fast-buffer.ts library in a TypeScript project, you can follow these steps:

1. Install the fast-buffer.ts library as a dependency in your project using npm or yarn. You can do this by running the following command in your project directory:

npm install fast-buffer.ts

or

yarn add fast-buffer.ts

2. Import the FastBuffer class from the fast-buffer.ts library in your TypeScript file:

import { FastBuffer } from 'fast-buffer.ts';

3. Create a new instance of the FastBuffer class by passing the desired buffer size (in bytes) as an argument:

const buffer = new FastBuffer(1024); // create a 1KB buffer

4. You can now use the buffer instance to read from or write to the buffer, using the methods provided by the FastBuffer class. For example:

// write a string to the buffer
buffer.write('hello world');

// read the string from the buffer
const str = buffer.toString();
console.log(str); // prints "hello world"

The FastBuffer class provides a similar API to the built-in Buffer class, but with improved performance. It is recommended to use FastBuffer when you need to work with large buffers or perform many read/write operations on a buffer.
