Struct RippleState 

pub struct RippleState { /* private fields */ }

RippleState

Manage ripple animations and hover state for interactive UI components. Recommended use: create a single RippleState handle and clone it to share.

Parameters

• This type has no constructor parameters; create it with RippleState::new().

Examples

use tessera_ui_basic_components::ripple_state::RippleState;
let s = RippleState::new();
assert!(!s.is_hovered());
s.set_hovered(true);
assert!(s.is_hovered());

Implementations

impl RippleState

pub fn new() -> Self

Creates a new RippleState with default values.

Example

use tessera_ui_basic_components::ripple_state::RippleState;
let state = RippleState::new();

pub fn start_animation(&self, click_pos: [f32; 2])

Starts a new ripple animation from the given click position.

Arguments

• click_pos - The normalized [x, y] position (typically in the range [0.0, 1.0]) where the ripple originates.

Example

use tessera_ui_basic_components::ripple_state::RippleState;
let state = RippleState::new();
state.start_animation([0.5, 0.5]);

pub fn get_animation_progress(&self) -> Option<(f32, [f32; 2])>

Returns the current progress of the ripple animation and the origin position.

Returns Some((progress, [x, y])) if the animation is active, where:

• progress is a value in [0.0, 1.0) representing the animation progress.
• [x, y] is the normalized origin of the ripple.

Returns None if the animation is not active or has completed.

Example

use tessera_ui_basic_components::ripple_state::RippleState;
let state = RippleState::new();
state.start_animation([0.5, 0.5]);
if let Some((progress, center)) = state.get_animation_progress() {
    // Use progress and center for rendering
}

pub fn set_hovered(&self, hovered: bool)

Sets the hover state for the ripple.

Arguments

• hovered - true if the pointer is over the component, false otherwise.

Example

use tessera_ui_basic_components::ripple_state::RippleState;
let state = RippleState::new();
state.set_hovered(true);

pub fn is_hovered(&self) -> bool

Returns whether the pointer is currently hovering over the component.

Example

use tessera_ui_basic_components::ripple_state::RippleState;
let state = RippleState::new();
let hovered = state.is_hovered();

Trait Implementations

impl Clone for RippleState

fn clone(&self) -> RippleState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for RippleState

fn default() -> Self

Creates a new RippleState with all fields initialized to their default values.
