go - 在 golang 中清除 bytes.Buffer 的正确方法是什么？

Question

我正在尝试清除一个bytes.Buffer，但是文档中没有这个功能

也许我应该更新缓冲区？正确的做法是什么？

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

Answer 1

Package bytes

func (*Buffer) Reset

func (b *Buffer) Reset()

Reset resets the buffer so it has no content. b.Reset() is the same as b.Truncate(0).

func (*Buffer) Truncate

func (b *Buffer) Truncate(n int)

Truncate discards all but the first n unread bytes from the buffer. It panics if n is negative or greater than the length of the buffer.

buffer.Reset()
