Struct TcpSegmentRaw 

pub struct TcpSegmentRaw<B: SplitByteSlice> { /* private fields */ }

A partially-parsed and not yet validated TCP segment.

A TcpSegmentRaw shares its underlying memory with the byte slice it was parsed from or serialized to, meaning that no copying or extra allocation is necessary.

Parsing a TcpSegmentRaw from raw data will succeed as long as at least 4 bytes are available, which will be extracted as a TcpFlowHeader that contains the TCP source and destination ports. A TcpSegmentRaw is, then, guaranteed to always have at least that minimal information available.

TcpSegment provides a FromRaw implementation that can be used to validate a TcpSegmentRaw.

Implementations

impl<B: SplitByteSliceMut> TcpSegmentRaw<B>

pub fn set_src_port(&mut self, new: NonZeroU16)

Set the source port of the TCP packet.

pub fn set_dst_port(&mut self, new: NonZeroU16)

Set the destination port of the TCP packet.

pub fn update_checksum_pseudo_header_address<A: IpAddress>( &mut self, old: A, new: A, )

Update the checksum to reflect an updated address in the pseudo header.

impl<B: SplitByteSlice> TcpSegmentRaw<B>

pub fn flow_header(&self) -> TcpFlowHeader

Gets the flow header from this packet.

impl<B: SplitByteSlice + CloneableByteSlice> TcpSegmentRaw<B>

pub fn into_builder_options<A: IpAddress>( self, src_ip: A, dst_ip: A, ) -> Option<(TcpSegmentBuilder<A>, TcpOptionsRef<B>, B)>

Transform this TcpSegmentRaw into the equivalent builder, parsed options, and body.
