fn (c &TcpConn) addr() ?Addr

fn (mut c TcpConn) close() ?

fn (mut con TcpConn) get_blocking() bool

get_blocking returns whether the connection is in a blocking state, that is calls to .read_line, C.recv etc will block till there is new data arrived, instead of returning immediately.

fn (c &TcpConn) peer_addr() ?Addr

fn (c &TcpConn) peer_ip() ?string

fn (c TcpConn) read(mut buf []byte) ?int

fn (mut c TcpConn) read_deadline() ?time.Time

fn (mut con TcpConn) read_line() string

read_line is a simple, non customizable, blocking line reader.
It will always return a line, ending with CRLF, or just '', on EOF.
NB: if you want more control over the buffer, please use a buffered IO reader instead: io.new_buffered_reader({reader: io.make_reader(con)})

fn (c TcpConn) read_ptr(buf_ptr &byte, len int) ?int

fn (c &TcpConn) read_timeout() time.Duration

fn (mut con TcpConn) set_blocking(state bool) ?

set_blocking will change the state of the connection to either blocking, when state is true, or non blocking (false).
The default for net tcp connections is the non blocking mode.
Calling .read_line will set the connection to blocking mode.
