Struct ClickCountingInfo 

struct ClickCountingInfo {
    time: Option<Instant>,
    point: Option<Point2D<f32, CSSPixel>>,
    button: Option<MouseButton>,
    count: usize,
}

A data structure used for tracking the current click count. This can be reset to 0 if a mouse button event happens at a sufficient distance or time from the previous one.

From https://w3c.github.io/uievents/#current-click-count:

Implementations MUST maintain the current click count when generating mouse events. This MUST be a non-negative integer indicating the number of consecutive clicks of a pointing device button within a specific time. The delay after which the count resets is specific to the environment configuration.

Fields

time: Option<Instant>

point: Option<Point2D<f32, CSSPixel>>

button: Option<MouseButton>

count: usize

Implementations

impl ClickCountingInfo

fn reset_click_count_if_necessary( &mut self, button: MouseButton, point_in_frame: Point2D<f32, CSSPixel>, )

fn increment_click_count( &mut self, button: MouseButton, point: Point2D<f32, CSSPixel>, ) -> usize

Trait Implementations

impl Default for ClickCountingInfo

fn default() -> ClickCountingInfo

Returns the “default value” for a type.

impl MallocSizeOf for ClickCountingInfo

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Traceable for ClickCountingInfo

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
