Struct HitTestItem 

pub struct HitTestItem {
    pub point_in_viewport: LogicalPosition,
    pub point_relative_to_item: LogicalPosition,
    pub is_focusable: bool,
    pub is_virtual_view_hit: Option<(DomId, LogicalPosition)>,
    pub hit_depth: u32,
}

A single hit-test result for a regular (non-scroll) DOM node.

Fields

point_in_viewport: LogicalPosition

The hit point in the coordinate space of the “viewport” of the display item. The viewport is the scroll node formed by the root reference frame of the display item’s pipeline.

point_relative_to_item: LogicalPosition

The coordinates of the original hit test point relative to the origin of this item. This is useful for calculating things like text offsets in the client.

is_focusable: bool

Necessary to easily get the nearest VirtualView node

is_virtual_view_hit: Option<(DomId, LogicalPosition)>

If this hit is a VirtualView node, stores the VirtualViews DomId + the origin of the VirtualView

hit_depth: u32

Z-order depth from WebRender hit test (0 = frontmost/topmost in z-order). Lower values are closer to the user. This preserves the ordering from WebRender’s hit test results which returns items front-to-back.

Trait Implementations

impl Clone for HitTestItem

fn clone(&self) -> HitTestItem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HitTestItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for HitTestItem

fn eq(&self, other: &HitTestItem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for HitTestItem

fn partial_cmp(&self, other: &HitTestItem) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
