Struct ScrollGeometry 

pub struct ScrollGeometry {
    pub content_offset: (f64, f64),
    pub content_size: (f64, f64),
    pub content_insets: (f64, f64, f64, f64),
    pub container_size: (f64, f64),
    pub visible_rect: (f64, f64, f64, f64),
}

What a scroll view’s geometry looks like when it changes.

ScrollGeometry exports no accessors, but it does not need to: the fields are stored, and the metadata says where.

  +0   contentOffset  CGPoint
  +16  contentSize    CGSize
  +32  contentInsets  EdgeInsets  (top, leading, bottom, trailing)
  +64  containerSize  CGSize
  +80  visibleRect    CGRect      (origin then size)

Fields

content_offset: (f64, f64)

How far the content has been scrolled.

content_size: (f64, f64)

How large the scrollable content is.

content_insets: (f64, f64, f64, f64)

The insets around it, as (top, leading, bottom, trailing).

container_size: (f64, f64)

How large the scroll view itself is.

visible_rect: (f64, f64, f64, f64)

What part of the content is on screen, as (x, y, width, height).
