这种类型的golang字符串切片会泄漏底层字节数组中的内存吗？(Can this type of golang string slicing leak memory in underlying byte array?)

push

If you're thinking of a similar situation which can arise when you assign a result of a slice operation, but never append. There's no leak per say, as long as you understand the semantics of slicing.

s := make([]byte, 1024)
s = s[1000:]
fmt.Println(s, len(s), cap(s))

copy

This works the same with strings:

s = s[1020:]
// may leave the first 1000 bytes allocated

[]byte
