Struct timely::dataflow::channels::Message

pub struct Message<T, C> {
    pub time: T,
    pub data: C,
    pub from: usize,
    pub seq: usize,
}

A serializable representation of timestamped data.

Fields

time: T

The timestamp associated with the message.

data: C

The data in the message.

from: usize

The source worker.

seq: usize

A sequence number for this worker-to-worker stream.

Implementations

impl<T, C> Message<T, C>

pub fn default_length() -> usize

👎Deprecated: Use timely::buffer::default_capacity instead

Default buffer size.

impl<T, C: Container> Message<T, C>

pub fn new(time: T, data: C, from: usize, seq: usize) -> Self

Creates a new message instance from arguments.

pub fn push_at<P: Push<Message<T, C>>>(buffer: &mut C, time: T, pusher: &mut P)

Forms a message, and pushes contents at pusher. Replaces buffer with what the pusher leaves in place, or the container’s default element. The buffer is cleared.

Trait Implementations

impl<T, C> Bytesable for Message<T, C>

where T: Serialize + for<'a> Deserialize<'a>, C: ContainerBytes,

fn from_bytes(bytes: Bytes) -> Self

Wrap bytes as Self.

fn length_in_bytes(&self) -> usize

The number of bytes required to serialize the data.

fn into_bytes<W: Write>(&self, writer: &mut W)

Writes the binary representation into writer.

impl<T: Clone, C: Clone> Clone for Message<T, C>

fn clone(&self) -> Message<T, C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, C: Container, P: Pull<Message<T, C>>> Pull<Message<T, C>> for LogPuller<T, C, P>

fn pull(&mut self) -> &mut Option<Message<T, C>>

Pulls an element and provides the opportunity to take ownership.

fn recv(&mut self) -> Option<T>

Takes an Option<T> and leaves None behind.

impl<T: Eq + Data, CB, P, H> Push<Message<T, <CB as ContainerBuilder>::Container>> for Exchange<T, CB, P, H>

where CB: ContainerBuilder + for<'a> PushInto<<CB::Container as Container>::Item<'a>>, CB::Container: SizableContainer, P: Push<Message<T, CB::Container>>, for<'a> H: FnMut(&<CB::Container as Container>::Item<'a>) -> u64,

fn push(&mut self, message: &mut Option<Message<T, CB::Container>>)

Pushes element with the opportunity to take ownership.

fn send(&mut self, element: T)

fn push(&mut self, pair: &mut Option<Message<T, C>>)

Pushes element with the opportunity to take ownership.

fn send(&mut self, element: T)

Pushes element and drops any resulting resources.

fn done(&mut self)

Pushes None, conventionally signalling a flush.

impl<T: Data, C: Container + Data> Push<Message<T, C>> for Tee<T, C>

fn push(&mut self, message: &mut Option<Message<T, C>>)

Pushes element with the opportunity to take ownership.

fn send(&mut self, element: T)

Pushes element and drops any resulting resources.

fn done(&mut self)
