Implementations

impl AnimationPreset

pub fn fade_in(duration_ms: u32) -> MultiKeyframeAnimation

Fade in from transparent to opaque

pub fn fade_out(duration_ms: u32) -> MultiKeyframeAnimation

Fade out from opaque to transparent

pub fn scale_in(duration_ms: u32) -> MultiKeyframeAnimation

Scale in from small to full size with fade

pub fn scale_out(duration_ms: u32) -> MultiKeyframeAnimation

Scale out from full size to small with fade

pub fn pop_in(duration_ms: u32) -> MultiKeyframeAnimation

Pop in with slight overshoot

pub fn slide_in_left(duration_ms: u32, distance: f32) -> MultiKeyframeAnimation

Slide in from the left

pub fn slide_in_right(duration_ms: u32, distance: f32) -> MultiKeyframeAnimation

Slide in from the right

pub fn slide_in_top(duration_ms: u32, distance: f32) -> MultiKeyframeAnimation

Slide in from the top

pub fn slide_in_bottom( duration_ms: u32, distance: f32, ) -> MultiKeyframeAnimation

Slide in from the bottom

pub fn slide_out_left(duration_ms: u32, distance: f32) -> MultiKeyframeAnimation

Slide out to the left

pub fn slide_out_right( duration_ms: u32, distance: f32, ) -> MultiKeyframeAnimation

Slide out to the right

pub fn slide_out_top(duration_ms: u32, distance: f32) -> MultiKeyframeAnimation

Slide out to the top

pub fn slide_out_bottom( duration_ms: u32, distance: f32, ) -> MultiKeyframeAnimation

Slide out to the bottom

pub fn bounce_in(duration_ms: u32) -> MultiKeyframeAnimation

Bounce in with overshoot effect

pub fn bounce_out(duration_ms: u32) -> MultiKeyframeAnimation

Bounce out with squash effect

pub fn shake(duration_ms: u32, intensity: f32) -> MultiKeyframeAnimation

Shake horizontally (for error feedback)

pub fn pulse(duration_ms: u32) -> MultiKeyframeAnimation

Pulse (scale up and down)

pub fn spin(duration_ms: u32) -> MultiKeyframeAnimation

Spin rotation (full 360 degrees)

pub fn flip_in_x(duration_ms: u32) -> MultiKeyframeAnimation

Flip in on X axis

pub fn flip_in_y(duration_ms: u32) -> MultiKeyframeAnimation

Flip in on Y axis

pub fn zoom_in_rotate(duration_ms: u32) -> MultiKeyframeAnimation

Zoom in with slight rotation

pub fn drop_in(duration_ms: u32, drop_distance: f32) -> MultiKeyframeAnimation

Drop in from above with bounce

pub fn dialog_in(duration_ms: u32) -> MultiKeyframeAnimation

Dialog enter animation - subtle scale up from 95% with fade

More appropriate for modals/dialogs than scale_in which starts from 0%.

pub fn dialog_out(duration_ms: u32) -> MultiKeyframeAnimation

Dialog exit animation - subtle scale down to 95% with fade

pub fn grow_in(duration_ms: u32) -> MultiKeyframeAnimation

Gentle grow enter animation - very subtle scale (99% to 100%) with fade

Minimal scale change to reduce visual distortion while still providing a sense of the element “growing” into place. Good for content with text where scale artifacts are more noticeable.

pub fn grow_out(duration_ms: u32) -> MultiKeyframeAnimation

Gentle grow exit animation - very subtle scale with fade

pub fn expand_in(duration_ms: u32) -> MultiKeyframeAnimation

Expand enter animation - grows from slightly smaller with a subtle “pop”

Similar to grow_in but with a slight overshoot for a more dynamic feel. Scale goes from 98% → 100.5% → 100%.

pub fn expand_out(duration_ms: u32) -> MultiKeyframeAnimation

Expand exit animation - shrinks slightly with fade

pub fn dropdown_in(duration_ms: u32) -> MultiKeyframeAnimation

Dropdown/menu enter animation - slide down with fade

Appropriate for dropdowns, context menus, and other popup menus. Uses a slight downward slide for a natural “dropping” feel.

pub fn dropdown_out(duration_ms: u32) -> MultiKeyframeAnimation

Dropdown/menu exit animation - slide up with fade

pub fn context_menu_in(duration_ms: u32) -> MultiKeyframeAnimation

Context menu enter animation - subtle scale from origin with fade

Similar to dropdown but uses scale from a corner origin feel.

pub fn context_menu_out(duration_ms: u32) -> MultiKeyframeAnimation

Context menu exit animation - subtle scale with fade
