Struct HoverAlpha 

pub struct HoverAlpha {
    pub rest: f32,
    pub peak: f32,
}

Configuration for El::hover_alpha — the rest and peak alpha endpoints for a node whose opacity binds to the subtree interaction envelope (max of hover, focus, and press over the subtree rooted at this node).

rest is the drawn alpha when no descendant of this node is currently the active hover, focus, or press target. peak is the drawn alpha at full envelope. Linear interpolation between the two follows the eased subtree envelope (0..1).

Both fields are clamped to [0.0, 1.0] by El::hover_alpha. Typical use is rest < peak (“reveal on interaction”), but the representation accepts rest > peak (“fade out on interaction”) and sub-1.0 peaks for subtle affordances.

Fields

rest: f32

peak: f32

Trait Implementations

impl Clone for HoverAlpha

fn clone(&self) -> HoverAlpha

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HoverAlpha

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

Formats the value using the given formatter.

impl PartialEq for HoverAlpha

fn eq(&self, other: &HoverAlpha) -> 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.
