缓冲 用法 以下缓冲区提供了简单的独特行为，这些行为组成时可创建复杂的缓冲策略。 与github.com/djherbis/nio一起用于io.Pipe和io.Copy缓冲实现。 例如： import ( "github.com/djherbis/buffer" "github.com/djherbis/nio" "io/ioutil" ) // Buffer 32KB to Memory, after that buffer to 100MB chunked files buf := buffer . NewUnboundedBuffer ( 32 * 1024 , 100 * 1024 * 1024 ) nio . Copy ( w , r , buf ) // Reads from r, writes to buf, reads from buf writes to
