Implementations

impl EventKind

pub const fn event_type(&self) -> &'static str

pub fn qualified_event_type(&self) -> String

Returns the stable, display-oriented type identity for this event.

Built-in event kinds retain the same snake-case labels returned by Self::event_type. Plugin events are qualified with their registered plugin name and event type, separated by a dot. The two plugin-provided components are preserved as registered; no case folding or additional normalization is applied.
