InternetChecksum

rama::net::ip

Struct InternetChecksum 

pub struct InternetChecksum { /* private fields */ }
Available on crate feature net only.
Expand description

Incremental Internet checksum (RFC 1071).

Slice boundaries may occur between the two bytes of a word. Odd trailing bytes are padded with zero only when Self::finish is called.

Implementations§

§

impl InternetChecksum

pub const fn new() -> InternetChecksum

Start a checksum.

pub fn update(&mut self, bytes: &[u8])

Add bytes in network order.

pub fn finish(self) -> u16

Complemented checksum, suitable for writing in network byte order. Checking a complete valid message including its checksum yields zero.
