去符文类型的解释 [英] Go rune type explanation

问题描述

我发现它是int32的别名，目的是区分数字和字符值。

http://golang.org/pkg / builtin /＃rune

但我对符文这个词的含义感到困惑吗？例如uint == unsigned int

解决方案

但我对符文它代表 ？例如uint == unsigned int

符文代表字母。 （符文是一组相关字母中的字母，称为符文字母，用于在采用拉丁字母之前编写各种日耳曼语言。[Wikipedia]）。

如果一个变量在Go中有类型 rune ，那么你知道它是为了保存一个unicode代码点。 （ rune 比 codepoint ）更短更清晰。但它在技术上是一个int32，即它在内存中的表示是int32。

I have found rune type in Go and have a simple question but worth an explnation.

I fount that it is an alias for int32 and purpose is to distinguish number and character values.

http://golang.org/pkg/builtin/#rune

But I am confused with the term "rune" what actually it stands for ? e.g uint == unsigned int

Rune stands for letter. ("Runes" are the letters in a set of related alphabets known as runic alphabets, which were used to write various Germanic languages before the adoption of the Latin alphabet. [Wikipedia]).

If a variable has type rune in Go you know it is intended to hold a unicode code point. (rune is shorter and clearer than codepoint). But it is technical a int32, i.e. its representation in memory is that of an int32.
