Enum backplane::WriteStream

pub enum WriteStream {
    File(File),
    Udp((UdpSocket, SocketAddrV4)),
    Tcp(TcpStream),
    Null,
}

A write stream, wrapped in an enum to allow multiple write streams to be returned from functions while still allowing the calling function to defer the choice of stream.

This is the closed, static way to do this- the open, dynamic way would be trait objects.

Variants

File(File)Udp((UdpSocket, SocketAddrV4))Tcp(TcpStream)Null

Methods

impl WriteStream

pub fn stream_send(&mut self, packet: &Vec<u8>) -> Result<usize, String>
