数组和切片之间的转换

package main func main() { in := [16]int{1, 1, 1} tmp := make([]int, 16) copy(tmp, in[:]) tmp[0] = 2 print(in[0]) //1 print(tmp[0]) //2 } 如果你要复制数组，而不是直接引用的话

我知道了 参考：https://segmentfault.com/a/1190000005006351 ~~~ func byte2string2(in [16]byte) []byte { tmp := make([]byte, 0) x := (*[3]uintptr)(unsafe.Pointer(&tmp)) x[0] = uintptr(unsafe.Pointer(&in)) x[1] = 16 x[2] = 16 return tmp } ~~~

`in[:]`就是切片了。
