Struct io::IoContext

pub struct IoContext<Message>
where
    Message: Send + Sync + 'static,
{ /* private fields */ }

IO access point. This is passed to all IO handlers and provides an interface to the IO subsystem.

Implementations

impl<Message> IoContext<Message>

where Message: Send + Sync + 'static,

pub fn new(channel: IoChannel<Message>, handler: usize) -> IoContext<Message>

Create a new IO access point. Takes references to all the data that can be updated within the IO handler.

pub fn register_timer( &self, token: TimerToken, delay: Duration ) -> Result<(), IoError>

Register a new recurring IO timer. ‘IoHandler::timeout’ will be called with the token.

pub fn register_timer_once( &self, token: TimerToken, delay: Duration ) -> Result<(), IoError>

Register a new IO timer once. ‘IoHandler::timeout’ will be called with the token.

pub fn register_timer_once_nocancel( &self, token: TimerToken, delay: Duration ) -> Result<(), IoError>

Register a new IO timer once. ‘IoHandler::timeout’ will be called with the token. Do NOT cancel other timer on the same token after timeout.

pub fn clear_timer(&self, token: TimerToken) -> Result<(), IoError>

Delete a timer.

pub fn register_stream(&self, token: StreamToken) -> Result<(), IoError>

Register a new IO stream.

pub fn deregister_stream(&self, token: StreamToken) -> Result<(), IoError>

Deregister an IO stream.

pub fn update_registration(&self, token: StreamToken) -> Result<(), IoError>

Reregister an IO stream.

pub fn message(&self, message: Message) -> Result<(), IoError>

Broadcast a message to other IO clients

pub fn handle( &self, peer: usize, handler_id: usize, msg: Message ) -> Result<(), IoError>

pub fn channel(&self) -> IoChannel<Message>

Get message channel

pub fn unregister_handler(&self)

Unregister current IO handler.

Trait Implementations

impl<Message> Clone for IoContext<Message>

where Message: Send + Sync + 'static + Clone,

fn clone(&self) -> IoContext<Message>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
