ResponseStep

tilo_app::tokens::response

Struct ResponseStep 

pub struct ResponseStep {
    pub lift: f32,
    pub tint: f32,
    pub scale: f32,
    pub glow: f32,
}
Expand description

One state’s response: the four levers a theme may move.

Fields§

§lift: f32

How far the fill steps toward the next surface (1 one surface step, crate::tokens::Colors::lift_on).

§tint: f32

How much of the accent washes into the lift, 0..=0.25.

§scale: f32

The control’s scale about its own centre; below 1 it presses in.

§glow: f32

The lit inner edge’s opacity, 0..=0.5; 0 draws none.

Implementations§

§

impl ResponseStep

pub const LIFT_ADMITTED: RangeInclusive<f32>

How far a lift may step, in surface steps: never none, because a theme cannot remove the hover and press lift (docs/design-language.md, “Theming”).

pub const TINT_ADMITTED: RangeInclusive<f32>

How much accent a lift may carry.

pub const SCALE_ADMITTED: RangeInclusive<f32>

How far a control may scale about its centre.

pub const GLOW_ADMITTED: RangeInclusive<f32>

How strongly the lit inner edge may draw.

pub const HOVER_LIFT: f32 = 0.5

The stock hover lift, half a surface step.

pub const PRESS_SCALE: f32 = 0.97

The stock press scale.

pub const REST: ResponseStep

The stock idle response: no lift, no tint, no scale, no glow.

pub fn validate(&self) -> Result<(), &'static str>

Every lever finite and inside its admitted band.

pub fn at(&self, t: f32) -> ResponseStep

This step between the rest and self at t (0 at rest, 1 arrived), as the part motion’s progress moves it. A step that changes no lever is the lever’s value at rest.

pub fn is_rest(&self) -> bool

Whether nothing moves for this step: the rest state.
