Struct AnimationState 

pub struct AnimationState {
    pub enabled: bool,
    pub focus_flash: Spring,
    pub peek_badge: Spring,
    pub panel_ratio: Spring,
    pub modal_open: Spring,
    pub reveal_springs: Vec<Spring>,
    pub reveal_active: bool,
}

Centralized animation state for all spring-based animations in the TUI.

All springs are ticked on every CassMsg::Tick. When enabled is false (CASS_DISABLE_ANIMATIONS=1), springs snap instantly to their targets.

Fields

enabled: bool

Master kill-switch: false when CASS_DISABLE_ANIMATIONS=1.

focus_flash: Spring

Focus flash spring (0→1 = flash active → settled).

peek_badge: Spring

Peek badge spring (0→1 = badge visible → hidden).

panel_ratio: Spring

Panel resize spring (current → target split ratio, 0.0–1.0).

modal_open: Spring

Modal open spring (0 = closed, 1 = fully open).

reveal_springs: Vec<Spring>

Result list reveal progress per slot (up to MAX_ANIMATED_ITEMS).

reveal_active: bool

Whether a reveal sequence is actively playing.

Implementations

impl AnimationState

pub fn new(enabled: bool) -> Self

Create a new animation state. Pass false to disable all animations.

pub fn from_env() -> Self

Read CASS_DISABLE_ANIMATIONS from environment.

pub fn tick(&mut self, dt: Duration)

Tick all active springs by dt. If animations are disabled, snap to targets.

pub fn trigger_focus_flash(&mut self)

Trigger a focus flash (spring from 0→1).

pub fn show_peek_badge(&mut self)

Show peek badge (spring to 1), will need explicit hide.

pub fn hide_peek_badge(&mut self)

Hide peek badge (spring to 0).

pub fn set_panel_ratio(&mut self, target: f64)

Animate panel split ratio to a new target.

pub fn open_modal(&mut self)

Open a modal (spring to 1).

pub fn close_modal(&mut self)

Close a modal (spring to 0).

pub fn start_reveal(&mut self, count: usize)

Start a staggered reveal for count result items.

pub fn clear_reveal(&mut self)

Clear any in-flight reveal sequence.

pub fn reveal_progress(&self, idx: usize) -> f64

Get the reveal progress for item at index (0.0 = hidden, 1.0 = visible).

pub fn focus_flash_progress(&self) -> f32

Get the focus flash progress (0.0 = just triggered, 1.0 = settled).

pub fn peek_badge_progress(&self) -> f32

Get the peek badge visibility (0.0 = hidden, 1.0 = fully visible).

pub fn modal_progress(&self) -> f32

Get the modal open progress (0.0 = closed, 1.0 = fully open).

pub fn panel_ratio_value(&self) -> f64

Get the animated panel split ratio.

Trait Implementations

impl Debug for AnimationState

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

Formats the value using the given formatter.

impl Default for AnimationState

fn default() -> Self

Returns the “default value” for a type.
