Implementations

impl<'a> Repr<'a>

pub fn parse<T>(
packet: &Packet<&'a T>,
src_addr: &IpAddress,
dst_addr: &IpAddress,
checksum_caps: &ChecksumCapabilities
) -> Result<Repr<'a>>where
T: AsRef<[u8]> + ?Sized,

Parse a Transmission Control Protocol packet and return a high-level representation.

pub fn header_len(&self) -> usize

Return the length of a header that will be emitted from this high-level representation.

This should be used for buffer space calculations. The TCP header length is a multiple of 4.

pub fn buffer_len(&self) -> usize

Return the length of a packet that will be emitted from this high-level representation.

pub fn emit<T>(
&self,
packet: &mut Packet<&mut T>,
src_addr: &IpAddress,
dst_addr: &IpAddress,
checksum_caps: &ChecksumCapabilities
)where
T: AsRef<[u8]> + AsMut<[u8]> + ?Sized,

Emit a high-level representation into a Transmission Control Protocol packet.

pub const fn segment_len(&self) -> usize

Return the length of the segment, in terms of sequence space.

pub const fn is_empty(&self) -> bool

Return whether the segment has no flags set (except PSH) and no data.

Trait Implementations

impl<'a> Clone for Repr<'a>

fn clone(&self) -> Repr<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Repr<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Display for Repr<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq<Repr<'a>> for Repr<'a>

fn eq(&self, other: &Repr<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
