[−][src]Struct erdos::dataflow::stream::extract_stream::ExtractStream

pub struct ExtractStream<D> where
    D: Data + Deserialize<'a>,  { /* fields omitted */ }

Methods

impl<D> ExtractStream<D> where
    D: Data + Deserialize<'a>, [src]

pub fn new(node_id: NodeId, read_stream: &ReadStream<D>) -> Self[src]

pub fn get_id(&self) -> StreamId[src]

pub fn get_node_id(&self) -> NodeId[src]

pub fn try_read(&mut self) -> Option<Message<D>>[src]

Tries to read a message from a channel.

Returns an immutable reference, or None if no messages are available at the moment (i.e., non-blocking read).

pub fn read(&mut self) -> Option<Message<D>>[src]

Blocking read. Returns None if the stream doesn't have a receive endpoint.
