Struct ItemState 

pub struct ItemState {
    pub opacity: f32,
    pub y_offset: f32,
    pub scale: f32,
}

Animation state for a single list item

Fields

opacity: f32

Opacity (0.0 = invisible, 1.0 = fully visible)

y_offset: f32

Vertical offset in pixels (positive = down)

scale: f32

Scale factor (1.0 = normal size)

pub fn visible() -> Self

Create visible state (fully opaque, no offset, normal scale)

pub fn exit_end() -> Self

Create exit animation state (invisible, below, scaled down)

pub fn lerp(from: Self, to: Self, t: f32) -> Self

Interpolate between two states
