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)

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()

1@warl0ck Keep in mind that this is effectively like doing `b = b[:0]`, it doesn't actually "free" the internal buffer. – OneOfOne Jan 31 '16 at 06:03

@OneOfOne, so how would one actually clear the underlying array? – Dmytro Titov Feb 17 '20 at 14:38

Clear or free? @DmytroTitov – OneOfOne Mar 05 '20 at 17:40

“Free”, I guess. – Dmytro Titov Mar 05 '20 at 21:30

1How can I release the memory of the buffer ? – Lewis Chan Jul 10 '21 at 10:25

Go's GC will reclaim once the variable is not referenced any more. – subtleseeker Aug 22 '22 at 03:48
