-// Addr net.Addr

-// The Buffers fields represents a list of contiguous buffers, which
-// can be used for vectored IO, for example, putting a header and a
-// payload in each slice.
-// When writing, the Buffers field must contain at least one byte to
-// write.
-// When reading, the Buffers field will always contain a byte to read.
-//
-// The OOB field contains protocol-specific control or miscellaneous
-// ancillary data known as out-of-band data.
-// It can be nil when not required.
-//
-// The Addr field specifies a destination address when writing.
-// It can be nil when the underlying protocol of the endpoint uses
-// connection-oriented communication.
-// After a successful read, it may contain the source address on the
-// received packet.
-//
-// The N field indicates the number of bytes read or written from/to
-// Buffers.
-//
-// The NN field indicates the number of bytes read or written from/to
-// OOB.
-//
-// The Flags field contains protocol-specific information on the
-// received message.
