Expand description
A TCP option.
Implementations
impl TcpOption
[src]
impl TcpOption
[src]pub fn nop() -> Self
[src]
pub fn nop() -> Self
[src]NOP: This may be used to align option fields on 32-bit boundaries for better performance.
pub fn timestamp(my: u32, their: u32) -> Self
[src]
pub fn timestamp(my: u32, their: u32) -> Self
[src]Timestamp: TCP timestamps, defined in RFC 1323, can help TCP determine in which order packets were sent. TCP timestamps are not normally aligned to the system clock and start at some random value.
pub fn mss(val: u16) -> Self
[src]
pub fn mss(val: u16) -> Self
[src]MSS: The maximum segment size (MSS) is the largest amount of data, specified in bytes, that TCP is willing to receive in a single segment.
pub fn wscale(val: u8) -> Self
[src]
pub fn wscale(val: u8) -> Self
[src]Window scale: The TCP window scale option, as defined in RFC 1323, is an option used to increase the maximum window size from 65,535 bytes to 1 gigabyte.
pub fn sack_perm() -> Self
[src]
pub fn sack_perm() -> Self
[src]Selective acknowledgment (SACK) option, defined in RFC 2018 allows the receiver to acknowledge discontinuous blocks of packets which were received correctly. This options enables use of SACK during negotiation.
pub fn selective_ack(acks: &[u32]) -> Self
[src]
pub fn selective_ack(acks: &[u32]) -> Self
[src]Selective acknowledgment (SACK) option, defined in RFC 2018 allows the receiver to acknowledge discontinuous blocks of packets which were received correctly. The acknowledgement can specify a number of SACK blocks, where each SACK block is conveyed by the starting and ending sequence numbers of a contiguous range that the receiver correctly received.
