Rust Error Handling Cheatsheet - Result handling functions

Introduction to Rust error handling

Rust error handling is nice but obligatory. Which makes it sometimes plenty of code.

Functions return values of type Result that is "enumeration". In Rust enumeration means complex value that has alternatives and that alternative is shown with a tag.

Result is defined as Ok or Err. The definition is generic, and both alternatives have

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

• Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
• Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
• If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
• If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Rime+小鹤双拼+颜文字+笔画混合输入方案

概述

方案配置文件+详细说明：Rime+小鹤双拼+颜文字+笔画混合输入方案

实现的功能是：给小鹤双拼添加颜文字支持，直接打双拼出颜文字，支持模糊音，支持词频调整，同时不影响小鹤双拼自带的笔画反查。

要实现双拼+颜文字的功能网上已经有很多方法，但都有些弊端，这里分别简单介绍下：
