Enum ScrollRange 

#[non_exhaustive]
pub enum ScrollRange {
    Scene,
    Through,
    Enter,
    Exit,
}

Which stretch of scrolling a ScrollLink counts as going from 0 to 1.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Scene

The nearest ScrollScene around the element: 0 when the scene pins, 1 when it lets go. Outside a scene, the same as Self::Through.

Through

The element’s whole pass across the visible area: 0 when its top reaches the bottom edge, 1 when its bottom leaves through the top edge.

Enter

The element coming in: 0 when its top reaches the bottom edge, 1 when it is fully visible (or, if taller than the view, when its top reaches the top edge).

Exit

The element going out: 0 when its top reaches the top edge, 1 when its bottom does.
