Struct Event 

pub struct Event {
    pub pr: u64,
    pub head_sha: String,
    pub run_id: String,
    pub attempt: u32,
    pub at: u64,
    pub kind: EventKind,
}

2026-09-26: One line of a journey. Event::identity is (head_sha, run_id, attempt, kind): pr and at are left out, so the same event appended twice collapses when read.

Fields

pr: u64

head_sha: String

run_id: String

2026-09-26: The CI run that observed this; empty when absent from the JSON.

attempt: u32

2026-09-26: Which attempt of that run. Part of the identity, so a re-run is kept as a separate event.

at: u64

2026-09-26: Unix seconds. Not part of the identity.

kind: EventKind

Implementations

impl Event

pub fn identity(&self) -> String

2026-09-26: The deduplication key: head sha, run id, attempt and the serialised kind.

pub fn node_label(&self) -> &'static str

2026-09-26: The label field of this event’s node in crate::ledger::materialize.

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<'de> Deserialize<'de> for Event

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Event

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
