Struct TimelineContract 

pub struct TimelineContract {
    pub events: VecDeque<CockpitTimelineEvent>,
    pub capacity: usize,
}

Data contract for the Timeline cockpit panel.

Source of truth: aggregated from all other cockpit contracts. Events are pushed by EvidenceSnapshots::refresh() when it detects state transitions.

Answers: “What changed, when, and across which subsystem?”

Fields

events: VecDeque<CockpitTimelineEvent>

Ring buffer of recent timeline events (newest last).

capacity: usize

Maximum events to retain.

Implementations

impl TimelineContract

pub fn new() -> Self

pub fn push(&mut self, event: CockpitTimelineEvent)

pub fn has_data(&self) -> bool

Whether any events have been recorded.

pub fn len(&self) -> usize

Number of events in the buffer.

pub fn is_empty(&self) -> bool

Whether the buffer is empty.
