Struct Event 

#[non_exhaustive]
pub struct Event {

    pub kind: String,
    pub timestamp_ms: u64,
    pub route: Option<String>,
    pub consumer: Option<String>,
    pub endpoint: Option<String>,
    pub status: Option<u16>,
    pub listener: Option<String>,
    pub method: Option<String>,
    pub duration_ms: Option<f64>,
    pub attempts: Option<u32>,

    pub broken: bool,
    pub shed: bool,
    pub edge_id: Option<String>,
    pub attributes: Vec<(String, String)>,
}

A single analytics event.

Deliberately minimal and extensible: new fields are additive. kind selects the event type (e.g. request); optional route/consumer identifiers carry the common correlation keys, and attributes holds everything else as string pairs to avoid a schema lock-in at M1. The DW-043 request-completion fields (listener, method, duration, outcomes) were added additively so the embedded store consumes this type directly; attributes carries custom analytics dimensions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: String

Event type discriminator, e.g. request.

timestamp_ms: u64

Unix epoch milliseconds.

route: Option<String>

Route name, when the event is tied to a matched route.

consumer: Option<String>

Consumer name, when authenticated.

endpoint: Option<String>

Upstream endpoint the request was forwarded to, if any.

status: Option<u16>

Upstream response status code, if a response was produced.

listener: Option<String>

Listener that accepted the request (DW-043).

method: Option<String>

HTTP method (DW-043).

duration_ms: Option<f64>

End-to-end request duration in milliseconds (DW-043).

attempts: Option<u32>

Upstream attempts made (DW-043).

rate_limited: bool

The request was rejected by a rate limit (DW-043).

broken: bool

The request failed through an open breaker (DW-043).

shed: bool

The request was shed by admission control (DW-043).

edge_id: Option<String>

The edge instance ID this event originated from (SCALE-07, #186). None for single-process (OSS) deployments; set by the controller’s EmbeddedCollector when forwarding federated events from edges to the aggregate store.

attributes: Vec<(String, String)>

Additional string key/value data (custom dimensions ride here).

Implementations

impl Event

pub fn request_now() -> Self

Build a request event stamped with the current time.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl PartialEq for Event

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