Struct DataPacket 

pub struct DataPacket {
    pub kind: Symbol,
    pub payload: Expr,
}

An opaque structured payload: a kind-tagged arbitrary Expr value.

Used for application-defined traffic the fabric does not interpret, such as model events and rank frontiers (see StreamPacket::model_event and StreamPacket::rank_frontier).

Fields

kind: Symbol

Symbol categorizing the payload (for example stream/data/model-event).

payload: Expr

The application-defined payload expression.

Implementations

impl DataPacket

pub fn new(kind: Symbol, payload: Expr) -> Self

Builds a data packet from its kind symbol and payload expression.

pub fn to_expr(&self) -> Expr

Encodes the packet as a stream/packet/data Expr map.

Trait Implementations

impl Clone for DataPacket

fn clone(&self) -> DataPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataPacket

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DataPacket

impl PartialEq for DataPacket

fn eq(&self, other: &DataPacket) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
