综上,string与[]byte在底层结构上是非常的相近(后者的底层表达仅多了一个 cap 属性,因此它们在内存布局上是可对齐的),这也就是为何 builtin 中内置函数 copy 会有一种特殊情况copy(dst []byte, src string) int的原因了。 // The copy built-in function copies elements from a source slice into a //...
[]string:一个字符串的切片,可以包含多个字符串。 []byte:一个字节的切片,通常用于存储二进制数据或字符串的字节表示。 编写转换函数: go package main import ( "fmt" ) // StringSliceToBytesSlice converts a slice of strings to a slice of byte slices. func StringSliceToBytesSlice(strings []strin...

Problem: Each time converting a bytes to string involves a memory allocation, caused by the design immutable string and mutable bytes. Investigation: Logically, a constant string which embedded into binaries got limited usage. And the de...
In the code example, we convert the file_size variable, which has type int64, to a string with strconv.FormatInt. $ go run int2str2.go The file size is 1544466212 bytes Go int to string with fmt.SprintfAnother way to convert an integer to a string is to use the fmt.Sprintf function...
