Struct ScrollMetrics 

pub struct ScrollMetrics {
    pub viewport_h: f32,
    pub content_h: f32,
    pub max_offset: f32,
}

Layout snapshot for a scrollable node. Written each frame by apply_scroll_offset; read by the scrollbar thumb in draw_ops and by runtime’s thumb-drag plumbing. viewport_h is the scrollable’s inner-rect height (post-padding); content_h is the total height of its children; max_offset is (content_h - viewport_h).max(0.0).

Fields

viewport_h: f32

content_h: f32

max_offset: f32

Trait Implementations

impl Clone for ScrollMetrics

fn clone(&self) -> ScrollMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScrollMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScrollMetrics

fn default() -> ScrollMetrics

Returns the “default value” for a type.

impl PartialEq for ScrollMetrics

fn eq(&self, other: &ScrollMetrics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for ScrollMetrics

impl StructuralPartialEq for ScrollMetrics
