Struct Handler

pub struct Handler { /* private fields */ }

The standard, blocking TCP I/O handler.

This handler makes use of the standard, blocking std::net::TcpStream to read from and write to TCP streams.

Implementations

impl Handler

pub fn new(host: impl AsRef<str>, port: u16) -> Result<Self>

Builds a new handler.

This function does perform I/O, as it connects to the TCP stream matching the given hostname and port.

pub fn read(&mut self, flow: impl AsMut<State>) -> Result<()>

Processes the read::Io::Read request.

This function reads synchronously a chunk of bytes from the inner TCP stream to its inner state read buffer, then set how many bytes have been read.

pub fn write(&mut self, flow: impl AsMut<State>) -> Result<()>

Processes the write::Io::Write request.

This function writes synchronously bytes to the inner TCP stream from its inner state write buffer, then set how many bytes have been written.
