pub struct EventQuery<'a> { /* private fields */ }

Query handle for an Event node in the chronicle graph.

Provides methods to inspect participants, location, causal chains, consequences, and state changes.

Implementations

impl<'a> EventQuery<'a>

pub fn data(&self) -> &'a Event

Returns a reference to the underlying Event data.

pub fn participants(&self) -> Vec<&'a Participant>

All participants in this event.

pub fn participants_by_role(&self, role: Role) -> Vec<&'a Participant>

Participants filtered by role.

pub fn location(&self) -> Option<&'a Place>

The location of this event, if any.

pub fn caused_by(&self) -> Vec<&'a Event>

Direct causes of this event.

pub fn causal_chain(&self) -> Vec<&'a Event>

Full causal chain backward (BFS through caused_by).

pub fn consequences(&self) -> Vec<&'a Event>

Events caused by this one (forward consequences via CausedBy edges).

pub fn state_changes(&self) -> &[EventStateChange]
