Struct OverlayPosition 

pub struct OverlayPosition {
    pub x: f64,
    pub y: f64,
    pub placement: OverlayPlacement,
    pub fits: bool,
    pub trigger_visible: bool,
    pub arrow: f64,
}

Calculated overlay position.

Fields

x: f64

y: f64

placement: OverlayPlacement

fits: bool

True when the overlay fits inside the boundary without clamping.

trigger_visible: bool

True when the TRIGGER itself intersects the boundary.

A trigger that has scrolled out of view has no on-screen anchor, so clamping its overlay into the viewport would park a box somewhere the user is looking at unrelated content — which is exactly what a forced-open overlay did before this existed. Callers hide the overlay when this is false rather than rendering it detached.

arrow: f64

Arrow centre in overlay-local coordinates along the cross axis (x for top/bottom placements, y for start/end). Lets the caller keep the arrow pointing at the trigger even after the overlay box is clamped to the viewport — the job Popper.js does for Bootstrap’s own overlays.
