Implementations

impl TcpSegmentMut<'_>

pub fn checksum_is_valid_ipv4( &self, source: Ipv4Address, destination: Ipv4Address, ) -> Result<bool, TcpChecksumError>

pub fn update_checksum_ipv4( &mut self, source: Ipv4Address, destination: Ipv4Address, ) -> Result<(), TcpChecksumError>

Recomputes this TCP segment’s IPv4 pseudoheader checksum.

impl TcpSegmentMut<'_>

pub fn checksum_is_valid_ipv6( &self, source: Ipv6Address, destination: Ipv6Address, ) -> Result<bool, TcpChecksumError>

Checks this TCP segment against its IPv6 pseudoheader.

pub fn update_checksum_ipv6( &mut self, source: Ipv6Address, destination: Ipv6Address, ) -> Result<(), TcpChecksumError>

Recomputes this TCP segment’s IPv6 pseudoheader checksum.
