Struct GatewayEvent 

pub struct GatewayEvent { /* private fields */ }

Represents one event emitted during a GatewayRun.

Each event has its own id, the id of the run it belongs to, a monotonic sequence within that run, a Symbol kind, an arbitrary Expr payload, and a creation timestamp.

Implementations

impl GatewayEvent

pub fn new( id: impl Into<String>, run_id: impl Into<String>, sequence: u64, kind: impl Into<Symbol>, payload: Expr, created_at_ms: u64, ) -> Self

Builds an event for a run from its id, parent run id, sequence number, kind, payload, and creation timestamp.

pub fn id(&self) -> &str

Returns the event id.

pub fn run_id(&self) -> &str

Returns the id of the run this event belongs to.

pub fn sequence(&self) -> u64

Returns the event’s sequence number within its run.

pub fn kind(&self) -> &Symbol

Returns the event kind symbol.

pub fn payload(&self) -> &Expr

Returns the event payload expression.

pub fn created_at_ms(&self) -> u64

Returns the creation timestamp in milliseconds.

pub fn to_expr(&self) -> Expr

Projects the event into its canonical Expr map representation.

Trait Implementations

fn claims( &self, _cx: &mut Cx, _pattern: &ClaimPattern, _sink: &mut dyn ClaimSink, ) -> Result<(), Error>

Emit the object’s claims matching pattern into sink.

fn snapshot(&self, _cx: &mut Cx) -> Result<Option<Datum>, Error>

Optional content-addressable snapshot of the object’s state.

impl ObjectCompat for GatewayEvent

fn as_expr(&self, _cx: &mut Cx) -> Result<Expr>

Expression form of the object; defaults to an opaque extension node.

fn class(&self, cx: &mut Cx) -> Result<Value, Error>

Class object this value belongs to; defaults to nil.

fn as_callable(&self) -> Option<&dyn Callable>

Callable view, if the object can be invoked.

fn as_class(&self) -> Option<&dyn Class>

Class view, if the object is a class.

fn as_shape(&self) -> Option<&dyn Shape>

Shape view, if the object is a shape.

fn as_object_encoder(&self) -> Option<&dyn ObjectEncode>

Object-encoder view, if the object encodes other objects.

fn as_read_constructor(&self) -> Option<&dyn ReadConstructor>

Read-constructor view, if the object decodes data forms.

fn as_number_domain(&self) -> Option<&(dyn NumberDomain + 'static)>

Number-domain view, if the object is a number domain.

fn as_number_value(&self) -> Option<&dyn NumberValue>

Number-value view, if the object is a domain number.

fn as_eval_fabric(&self) -> Option<&dyn EvalFabric>

Eval-fabric view, if the object is a distributed eval surface.

fn as_stream(&self) -> Option<&dyn Stream>

Stream view, if the object is a stream.

Thunk view, if the object is a deferred computation.

fn as_list(&self) -> Option<&(dyn ListValue + 'static)>

List view, if the object is a list value.

fn as_table_impl(&self) -> Option<&(dyn Table + 'static)>

Table-implementation view, if the object is a table.

fn as_dir(&self) -> Option<&(dyn Dir + 'static)>

Directory view, if the object is a directory.

fn truth(&self, _cx: &mut Cx) -> Result<bool, Error>

Truthiness of the object; defaults to true.

fn publish_shape_satisfaction_claims( &self, _cx: &mut Cx, _shape: &Ref, ) -> Result<bool, Error>

Publish claims asserting that the object satisfies shape; returns whether any were published.

fn as_table(&self, cx: &mut Cx) -> Result<Value, Error>

Project the object into a table value; the default exposes its display.

impl PartialEq for GatewayEvent

fn eq(&self, other: &GatewayEvent) -> 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.
