What's the right way to clear a bytes.Buffer in golang?

问题

我正在尝试清空一个bytes.Buffer,但是文档中没有这样的函数。

也许我应该重新创建一个新的缓冲区?应该如何正确地做呢?

buffer = bytes.NewBufferString("")
buffer.Grow(30000)
英文:

I'm trying to clear a bytes.Buffer, but there's no such function in the document

Maybe I should just renew the buffer? What's the right way to do it?

buffer   = bytes.NewBufferString("")
buffer.Grow (30000)
