Struct ButtonClickState 

struct ButtonClickState {
    down_point: Option<Point2D<f32, CSSPixel>>,
    last_click_time: Option<Instant>,
    last_click_point: Option<Point2D<f32, CSSPixel>>,
    click_count: usize,
}

A data structure used for tracking the state of a particular mouse button’s clicks. This is used to determine when to fire click events and for click counting. Click counts 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

down_point: Option<Point2D<f32, CSSPixel>>

last_click_time: Option<Instant>

last_click_point: Option<Point2D<f32, CSSPixel>>

click_count: usize
