Struct EventPath 

pub struct EventPath { /* private fields */ }

The propagation path for an event.

Built from target node up to the document root. Stored as (index, generation) pairs for liveness validation.

Index 0 = target, Index N = root (same order as Chrome). Capture iterates in reverse. Bubble iterates forward.

Implementations

impl EventPath

pub fn len(&self) -> usize

Number of nodes in the path.

pub fn is_empty(&self) -> bool

Is the path empty? (target was dead)

pub fn target(&self) -> Option<(u32, u32)>

The target node (first entry).

pub fn target_index(&self) -> usize

Index of the target in the path (always 0 if non-empty).

pub fn capture_order(&self) -> impl Iterator<Item = (usize, u32, u32)> + '_

Iterate in capture order (root -> target).

pub fn bubble_order(&self) -> impl Iterator<Item = (usize, u32, u32)> + '_

Iterate in bubble order (target -> root).

pub fn get(&self, pos: usize) -> Option<(u32, u32)>

Get entry at position.
