Struct AnimationState 

pub struct AnimationState {
    pub spinner_tick: u64,
    /* private fields */
}

Animation state kept separate from App (render-layer concern).

Fields

spinner_tick: u64

Implementations

impl AnimationState

pub fn new() -> Self

pub fn is_animating(&self, app: &App) -> bool

Whether any animation is running.

pub fn has_checking_hosts(&self, app: &App) -> bool

Whether any host has PingStatus::Checking (spinner needs ticking).

pub fn has_reachable_hosts(&self, app: &App) -> bool

Whether any host is currently Reachable. Drives the “breathing” pulse on online indicators: when at least one host is alive the main loop runs at 80ms tick rate so online_dot_pulsing can advance smoothly. Slow/Unreachable/Checking deliberately do NOT pulse — only confirmed-online gets the subtle live signal.

pub fn tick_spinner(&mut self)

Advance spinner tick. Called from main loop at ~80ms intervals.

pub fn overlay_anim_progress(&self) -> Option<f32>

Current overlay animation progress (0.0 = hidden, 1.0 = fully visible).

pub fn tick_overlay_anim(&mut self)

Tick overlay animation: clean up when complete.

pub fn detail_anim_progress(&mut self) -> Option<f32>

Current detail panel animation progress (0.0 = closed, 1.0 = open).

pub fn note_tunnel_panel_target(&mut self, visible: bool)

Notify the animator that the tunnel detail panel target visibility has been computed for this frame. Starts a slide animation when the target flips, preserving the in-flight progress so a flap mid-animation reverses smoothly.

pub fn tunnel_panel_anim_progress(&mut self) -> Option<f32>

Current tunnel-panel height animation progress (0.0 = collapsed, 1.0 = full height). Returns None when no animation is in flight.

pub fn detect_transitions(&mut self, app: &mut App)

Detect overlay open/close transitions and start animations.

Trait Implementations

impl Default for AnimationState

fn default() -> Self

Returns the “default value” for a type.
