Struct ScrollSpec 

pub struct ScrollSpec {

    pub floating: bool,
    pub bar_width: f32,
    pub handle_min_length: f32,
    pub bar_inner_margin: f32,
    pub bar_outer_margin: f32,
    pub floating_width: f32,
    pub floating_allocated_width: f32,
    pub foreground_color: bool,
    pub dormant_background_opacity: f32,
    pub active_background_opacity: f32,
    pub interact_background_opacity: f32,
    pub dormant_handle_opacity: f32,
    pub active_handle_opacity: f32,
    pub interact_handle_opacity: f32,
    pub visibility: ScrollVisibility,
}

All 14 ScrollStyle knobs + the visibility default, serialisable. The six opacity fields make a macOS bar dormant-invisible until hover.

Fields

floating: bool

bar_width: f32

handle_min_length: f32

bar_inner_margin: f32

bar_outer_margin: f32

floating_width: f32

floating_allocated_width: f32

foreground_color: bool

dormant_background_opacity: f32

active_background_opacity: f32

interact_background_opacity: f32

dormant_handle_opacity: f32

active_handle_opacity: f32

interact_handle_opacity: f32

visibility: ScrollVisibility

Implementations

impl ScrollSpec

pub fn windows() -> Self

Windows: solid, always-present, chunky bar.

pub fn macos() -> Self

macOS: floating, slim, dormant-invisible, fades in on hover/scroll.

pub fn device() -> Self

Device: solid, high-contrast, always visible (no fade to find in sun).

pub fn to_scroll_style(&self) -> ScrollStyle

Build an egui ScrollStyle, modelling the 14 work-order fields and inheriting egui’s defaults for the rest (content_margin, fade, which 0.34 added beyond the spec). Starting from solid()/floating() keeps us forward-compatible with future egui fields.

Trait Implementations

impl Clone for ScrollSpec

fn clone(&self) -> ScrollSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScrollSpec

impl Debug for ScrollSpec

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

Formats the value using the given formatter.

impl Default for ScrollSpec

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScrollSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScrollSpec

fn eq(&self, other: &ScrollSpec) -> 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 Serialize for ScrollSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
