Struct HitTestItem

pub struct HitTestItem {
    pub pipeline: PipelineId,
    pub tag: ItemTag,
    pub point_in_viewport: LayoutPoint,
    pub point_relative_to_item: LayoutPoint,
}

Describe an item that matched a hit-test query.

Fields

pipeline: PipelineId

The pipeline that the display item that was hit belongs to.

tag: ItemTag

The tag of the hit display item.

point_in_viewport: LayoutPoint

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: LayoutPoint

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.

Trait Implementations

impl Clone for HitTestItem

fn clone(&self) -> HitTestItem

Returns a copy 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<'de> Deserialize<'de> for HitTestItem

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for HitTestItem

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
