Struct Popper 

pub struct Popper {
    pub anchor_bounds: Bounds<Pixels>,
    pub placement: Placement,
    pub offset: Pixels,
}

Runtime state used by Liora popper behavior.

Fields

anchor_bounds: Bounds<Pixels>

Bounds of the trigger element used for popper positioning.

placement: Placement

Preferred placement relative to the trigger or anchor.

offset: Pixels

Pixel offset applied after popper placement is resolved.

Implementations

impl Popper

pub fn calculate_position(&self, content_size: Size<Pixels>) -> Point<Pixels>

Calculates the floating element origin for the configured anchor and placement.

pub fn calculate_position_with_flip( &self, content_size: Size<Pixels>, viewport: Bounds<Pixels>, ) -> (Point<Pixels>, Placement)

Calculates the floating element origin and flips placement when needed to fit the viewport.
