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...
string与[]byte的转换 string与slice的结构本质上是一样的,可以直接强制转换: import ( "reflect" "unsafe" ) // copy from prometheus source code // NoAllocString convert []byte to string func NoAllocString(bytes []byte) string { return *(*string)(unsafe.Pointer(&bytes)) ...
