Struct ModalAnimationState 

pub struct ModalAnimationState { /* private fields */ }

Current animation state for a modal.

Tracks progress through open/close animations and computes interpolated values for scale, opacity, and position offset.

Implementations

impl ModalAnimationState

pub fn new() -> Self

Create a new animation state (closed, no animation).

pub fn open() -> Self

Create a state that starts fully open (for testing or instant open).

pub fn phase(&self) -> ModalAnimationPhase

Get the current phase.

pub fn progress(&self) -> f64

Get the raw progress value (0.0 to 1.0).

pub fn backdrop_progress(&self) -> f64

Get the backdrop progress value (0.0 to 1.0).

pub fn is_visible(&self) -> bool

Check if the modal is visible (should be rendered).

pub fn is_animating(&self) -> bool

Check if animation is in progress.

pub fn is_open(&self) -> bool

Check if the modal is fully open.

pub fn is_closed(&self) -> bool

Check if the modal is fully closed.

pub fn set_reduced_motion(&mut self, enabled: bool)

Set reduced motion preference.

pub fn start_opening(&mut self)

Start opening animation.

If already opening or open, this is a no-op. If closing, reverses direction and preserves momentum.

pub fn start_closing(&mut self)

Start closing animation.

If already closing or closed, this is a no-op. If opening, reverses direction and preserves momentum.

pub fn force_open(&mut self)

Force the modal to be fully open (skip animation).

pub fn force_close(&mut self)

Force the modal to be fully closed (skip animation).

pub fn tick(&mut self, delta: Duration, config: &ModalAnimationConfig) -> bool

Advance the animation by the given delta time.

Returns true if the animation phase changed (e.g., Opening → Open).

pub fn eased_progress(&self, config: &ModalAnimationConfig) -> f64

Get the current eased progress for content animation.

pub fn eased_backdrop_progress(&self, config: &ModalAnimationConfig) -> f64

Get the current eased progress for backdrop animation.

pub fn current_scale(&self, config: &ModalAnimationConfig) -> f64

Get the current scale factor for the modal content.

Returns a value in [min_scale, 1.0].

pub fn current_opacity(&self, config: &ModalAnimationConfig) -> f64

Get the current opacity for the modal content.

Returns a value in [0.0, 1.0].

pub fn current_backdrop_opacity(&self, config: &ModalAnimationConfig) -> f64

Get the current backdrop opacity.

Returns a value in [0.0, 1.0] to be multiplied with the backdrop’s configured opacity.

pub fn current_y_offset( &self, config: &ModalAnimationConfig, modal_height: u16, ) -> i16

Get the current Y offset for the modal content.

Returns an offset in cells (negative = above final position).

pub fn current_values( &self, config: &ModalAnimationConfig, modal_height: u16, ) -> (f64, f64, f64, i16)

Get all current animation values at once.

Returns (scale, opacity, backdrop_opacity, y_offset).

Trait Implementations

Performs copy-assignment from source.

impl Debug for ModalAnimationState

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

impl Default for ModalAnimationState

fn default() -> Self

Returns the “default value” for a type.
