Struct scuttlebutt::channel::HashChannel

pub struct HashChannel<R, W> { /* private fields */ }

An instantiation of the AbstractChannel trait which computes a running hash of all bytes read from and written to the channel.

Implementations

impl<R: Read, W: Write> HashChannel<R, W>

pub fn new(reader: R, writer: W) -> Self

Make a new HashChannel from a reader and a writer.

pub fn finish(self) -> [u8; 32]

Consume the channel and output the hash of all the communication.
