Go的[]rune 和 []byte的差別

Go的[]rune 和 []byte的差別

  []rune 和 []byte源碼

// 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.      

  原來是 ​

​byte​

​​ 表示一個位元組,​

​rune​

​ 表示四個位元組,那麼就可以得出了結論了,來看一段代碼,使用中文字元串

  1、[]rune (四個位元組)

  2、[]byte (一個位元組)
