Trait tk_sendfile::Destination

pub trait Destination: Write + Send {
    fn write_file<O: FileOpener>(&mut self,
                             file: &mut Sendfile<O>)
                             -> Result<usize, Error>;
    fn poll_write(&mut self) -> Async<()>;
}

A trait that represents anything that file can be sent to

The trait is implemented for TcpStream right away but you might want to implement your own thing, for example to prepend the data with file length header

Required Methods

fn write_file<O: FileOpener>(&mut self,
                             file: &mut Sendfile<O>)
                             -> Result<usize, Error>

This method does the actual sendfile call

Note: this method is called in other thread

fn poll_write(&mut self) -> Async<()>

Test to see if this object may be writable
