Types

type BufAllocator

type BufAllocator struct {
	// contains filtered or unexported fields
}

BufAllocator helps you manage multi chunks in one []byte.

Alloc allocates a new chunk with the specified size n.

func (*BufAllocator) Reset

func (b *BufAllocator) Reset()

Reset resets the buffer to later reuse
