Struct EventContext 

pub struct EventContext { /* private fields */ }

Mutable dispatch state passed to event handlers.

Uses Cell for interior mutability — handlers can call stop_propagation() etc. through a shared reference. Safe because dispatch is single-threaded.

Chrome equivalence

Chrome field	Kozan field
event_phase_	phase
propagation_stopped_	propagation_stopped
immediate_propagation_stopped_	immediate_stopped
default_prevented_	default_prevented

target_	target

Implementations

impl EventContext

pub fn target(&self) -> u32

The target node (where the event was originally dispatched).

pub fn current_target(&self) -> u32

The node currently being processed in the dispatch path.

pub fn phase(&self) -> Phase

The current dispatch phase.

pub fn stop_propagation(&self)

Stop propagation to subsequent nodes. Remaining listeners on the current node still fire. (Chrome: stopPropagation())

pub fn stop_immediate_propagation(&self)

Stop propagation AND prevent remaining listeners on the current node. (Chrome: stopImmediatePropagation())

pub fn prevent_default(&self)

Prevent the default action for this event. Does NOT stop propagation — all listeners still fire. (Chrome: preventDefault())

pub fn is_propagation_stopped(&self) -> bool

Was stop_propagation() or stop_immediate_propagation() called?

pub fn is_immediate_stopped(&self) -> bool

Was stop_immediate_propagation() called?

pub fn is_default_prevented(&self) -> bool

Was prevent_default() called?
