Struct comms::client::Client
[−]
[src]
pub struct Client<I, C> where I: Clone + Send + Debug + 'static,
C: Sink + Stream + 'static { /* fields omitted */ }
Handles communication with a single server client.
This is the basic 'unit' around which comms
is constructed. It handles
communication with a single client, e.g., a single TCP socket. It stores
an ID and closes the connection if the provided Sink
or Stream
errors.
In addition this supports timeouts on receiving data. The Timeout
enum
allows specifying whether to have a timeout and whether the client should
be disconnected should the timeout not be met.

fn new_from_split(id: I, tx: T, rx: R) -> Client<I, Unsplit<T, R>>
Create a new client from separate Sink
and Stream
.

and a Stream
.

fn new(id: I, tx_rx: C) -> Client<I, C>
Create a new client from a Sink + Stream
.
Created from the ID, a timeout strategy, and a Sink + Stream
.
fn id(&self) -> I
Get a clone of the client ID.
fn rename<J>(self, new_id: J) -> Client<J, C> where J: Clone + Send + Debug + 'static
Change the client's ID. The new ID can be of a different type.
fn transmit(self, msg: C::SinkItem) -> Transmit<I, C>
Future that transmits a single message.
If this succeeds the Item is a Client. If the transmission fails the Error is a Client which has dropped its connection.
handle.spawn(client.transmit('h') .and_then(|client| client.transmit('e')) .and_then(|client| client.transmit('l')) .and_then(|client| client.transmit('l')) .and_then(|client| client.transmit('o')) .map(|client| println!("sent hello to {}.", client.id()); ()) .map_err(|client| println!("sending hello to {} failed.", client.id()); ()));
fn receive(self) -> Receive<I, C>
Future that tries to receive a single message.
fn is_connected(&self) -> bool
Is the client connected?
fn is_disconnected(&self) -> Option<&Disconnect<C::SinkError, C::Error>>
Get disconnection cause if the client is disconnected.
fn close(&mut self) -> bool
Force the Client to disconnect if a connection is active.
Returns whether an active connection was disconnected.
fn into_inner(self) -> (I, Result<C, Disconnect<C::SinkError, C::Error>>)
Retrieve the client ID and the current state of the connection.
