Go的[]rune 和 []byte的区别
Go的[]rune 和 []byte的区别
[]rune 和 []byte源码
// byte is an alias for uint8 and is equivalent to uint8 in all ways. It is // used, by convention, to distinguish byte values from 8-bit unsigned // integer values. type byte = uint8 // rune is an alias for int32 and is equivalent to int32 in all ways. It is // used, by convention, to distinguish character values from integer values. type rune = int32
原来是 byte
表示一个字节,rune
表示四个字节,那么就可以得出了结论了,来看一段代码,使用中文字符串
1、[]rune (四个字节)
[]rune 把字符转换成Unicode码点
